			"shape_cmd" field (instead of the shape_cmd values)
			This is needed because the roadmap field "shape_cmd"
			is used to figure out the output array size.
V 1.02 12-Oct-92 MDM - Modification to allow non-standard image shapes
			to be saved.  Previous restriction was that nx*ny

                       bit6=1 => Unix compress = default, bit7=1 => gzip compress.

OPTIONAL KEYWORD INPUT:
	dir	- The output directory (option not to have to
		  specify it in the filename)
	append	- If set, append the dataset to an existing file
		  If the file does not exist, it will create a new
		  file.
	skipmap	- If set, do not generate the roadmap for the file.
		  This would be used when writing out a large number
		  of datasets (typically PFI) and using the /APPEND
		  option.  The final call writing out the datasets
		  will have to not have this switch set in order to
		  have the roadmap created and the file be readable.
	use_index_size - If set, look at the size of the image as
		  specified in the index and write out only that portion.
		  This is generally needed when saving FFI images and
		  there are 4x4 images embedded in a 512x512xN data
		  array.  The default is to save it how it is passed in
		  since it might have been processed and it's size
		  changed on purpose.
	progname - The name of the program that is calling SAV_SDA
	progverno - The version number of the program that is calling SAV_SDA
	fhead_input - The file header of the input files to the program
		  that is calling SAV_SDA so that the REFORMAT version 
		  number is saved in the output file header
	compress - If set, then compress the data portion of the data.
		  If it is a scalar, then it is used for all images.
		  If it is an array, then it applies to each of the images.

       type_comp - Determines compression type used. 1 = Unix Compress, 
                    2 = gzip, Default = 1.
HISTORY:
	Written Sep-91 by M.Morrison
	11-Nov-91 MDM - Changed to allow to save only index if wanted.
			Need to pass data as undefined or a one element
			scalar.
			Also added the option to skip generating the map
			so that the writes are faster.  The last time it is
			called, the map should be written. - BECAREFUL
	12-Nov-91 MDM - Added "use_index_size" option so that if a matrix
			is passed and it had images that were padded because
			of a large image, the size of the image saved is the
			"original" image size.  The default is to save it as
			passed since it might have had it's size changed
			in another routine (change 4x4 to 2x2)
	 5-May-92 MDM - Added document header
V 1.00	24-Aug-92 MDM - Added "progverno", "progname" and "fhead_input" 
			keyword inputs
V 1.01 24-Aug-92 MDM - Added /shape_sav to WRTSXTMAP call -- 
       		copy the shape_sav values to the roadmap
			"shape_cmd" field (instead of the shape_cmd values)
			This is needed because the roadmap field "shape_cmd"
			is used to figure out the output array size.
V 1.02 12-Oct-92 MDM - Modification to allow non-standard image shapes
			to be saved.  Previous restriction was that nx*ny
			be a multiple of 16 (the file record size)
V 1.03	 6-Dec-93 MDM - Modification to WRTSXTMAP to use the old roadmap instead
			of re-generating the whole thing.
V 1.04  7-Dec-93 MDM - Modified not to read the roadmap when /append and
			/skipmap is set.
	26-Jan-94 AKT - Modified to add /block keyword to openu call.  mk_sfd
			crashed because couldn't position within last 512 bytes.
	 9-Mar-94 MDM - Modified the header information
V 1.10	 7-Mar-95 MDM - Added /COMPRESS option
		      - Added /QDEBUG
       12-Dec 97 PGS - Added type_comp keyword, wrote compression type to 
                       bits 6 & 7 of index0.gen.data_word_type. 
                       bit6=1 => Unix compress = default, bit7=1 => gzip compress. 
       25-Jan-98 SLF - define COMPRESS if not already done
        5-May-99 SLF - add /NOLOWER to open_da_file call
                       (permit upper case file/path names)

   Notes: 
	The pair of routines [sav_string/get_string] were developed to allow
	saving and restoring of several yohkoh parameters (ex: !path) to help 
	manage the Yohkoh idl environment but they are generic in nature and 
	other uses may be considered.  They can be used in conjunction with 
	arr2str and str2arr to allow storing of string 'arrays'

 MODIFICATION HISTORY:
	version 1.0	92.11.30 (Mon)
	version 1.1	92.12.03 (Thu)
		Return value of this function was changed from sbt(4,*) to 
		sbt(4,64,4,*) so as to ensure compatibility with 
		hxt_hs_hardness.pro and hxt_halfsec.pro.
		In fact, ver 1.0 does not match with any of .pro in hxt_proc/.
	version 1.2	93.02.16 (Tue)
		Unit of accum_time is changed to 'sec' instead of 'msec'.
		Usage :
			IDL > sbt = sbt_hxt_data(index,data,bgd)
			where  data = bytarr(4,64,4,*) ... raw 'data' from 
			RF database.
			bgd  = HXT BGD structure.

	MAKE SURE VER 1.1 DOES NOT GIVE CORRECT ANSWER AT ALL (LOTS OF BUGS 
	IN IT).
	version 1.3	93.02.17 (Wed)
		Option var added.
		Usage :
			IDL > sbt = sbt_hxt_data(index,data,bgd,var=var)
			where  var = fltarr(4,64,4,*), gives variance for 
			each 'sbt'.
	version 1.4	97.06.25 (Wed)
		Array-type for the bgd variable was added.

 PURPOSE
	To compute the azimuthally-averaged radial intensity distribution from
	some origin -- either the center of the sun or an input location.
	Radial totals, not averaged over azimuth, can be returned also for
	use in SXT_TEEM which requires actual total DN if error bars are
	be put on the temperatures.
	   Signal averages or totals over specified sectors also an option.

 INPUT
       image - Fully corrected image.
	Either:  index, origin or both.
 OUTPUT TO SCREEN
	If the keyword sectparam is not set then output of the following
	form is written to the screen:
		The slope of the fit is     -2.03562
		Fitted expression:   Signal =  6.6e+06*R^(-2.04)   per pixel.
 OPTIONAL OUTPUT
	xxx - linear array of R values for plotting
	sig - array of signal values, averaged over azimuth, function of R
		units are DN/pixel for pixel size in image
		Used for plotting signal vs. R
       rr - array of radii of all distances from origin
		units are pixels (pixel size of image)
       xy - array of pixels included in the analysis
	unc_sig - compression uncertainties on azimuthly averaged values
	fullsig - azimuthal totals, not averaged over azimuth, function of R
		for use with SXT_TEEM
	unc_fullsig - compression errors on azimuth totals
 OPTIONAL INPUT
	rr, return from first run and input for subsequent runs 
		to save time.
 OPTIONAL KEYWORD INPUT
	index - to permit getting suncenter from the data base
		and labelling of output figures
	origin - origin of coordinates for azimuth averaging, if this is
		 specified it takes priority over suncenter from index
		 but one or the other must be provided.

      infil = If set to a string array on input, the file names in "files"
              will be searched.  Otherwise all the data in the current path
              will be checked(!).  On output, the files variable will be 
              replaced by the actual list of files searched.
      ss = If defined on input, ss is used for initial data selection.
KEYWORD PARAMETERS
      reset = Ignore files,roadmap if they are already defined (force data
              to be read in)
      arcmin = specifies how close the field-of-view center should
               be to the active region (in arc minutes), default is 0.  The 
               size of the image is added to the arcmin value, so the default
               of zero implies that the point being tracked must be just 
               inside the FOV.  Negative values will force the AR well 
               insided the FOV.
      cdir_only = if set, look only at the files in the current directory
OUTPUTS:
      ss = array of the image indices which are close to the AR

COMMON BLOCKS:
SIDE EFFECTS:
RESTRICTIONS:
      FFI images are *always* selected.  Only PFI images are checked for a 
      position which matches the location of the active region.
PROCEDURE:
      The data are selected based upon their position (including differential
      rotation).
      No selection is done for different filters etc.  I assume this
      will come at some later step in the analysis process.

MODIFICATION HISTORY:
      T. Metcalf  May 04, 1992
             TRM  Feb 27, 1993  Since gt_fov_center.pro was updated, this
                                routine also needed to be updated.  It now
                                works with the new gt_fov_center.

			.dpe  = # of seconds in exposure away from the actual
				0 is perfect match, positive means DC
				is longer exposure than requested.
			.time = the number of days from the requested day.
			        positive is for DC images taken past
				the time of the input image
			.temp = the number of degress that the match is off
			.dpeval = the DPE value matched
METHOD:
	The program will try to make an exact match to the exposure
	level passed.  If it cannot match, it will take the next exposure
	larger which is available.  

	GET_DC_IMAGE can be called manually by passing "times", "res"
	and "dpe" using the keywords.  All three need to be passed, however
	it is possible to pass an array of times, but have res or dpe

HISTORY:
	Written 24-Aug-93 by M.Morrison (using GET_DC_IMAGE as starting point)
	Differences from GET_DC_IMAGE:
		* Combined GET_DC_WARM and GET_DC_IMAGE
		* Match on exposure duration in seconds, not DPE value
	25-Aug-93 (MDM) - Added "dc_filidx" to speed things up
	 1-Sep-93 (MDM) - Corrected a typo "dc_filidx2"
	16-Dec-93 (MDM) - Modified to break images into two categories
			  Those taken before 13-Nov-92 and those taken 
			  after.  Do not cross the line.
	26-Jan-94 (MDM) - Corrected error when trying to get SDW files and
			  they do not exist.
			- Modified the logic so that manual passing of the
			  temperature works properly
	31-Jan-94 (MDM) - Corrected 26-Jan-94 patch - there are cases when
			  the roadmap is passed in, which does not have the
			  temperature
       11-May-94 (SLF) - subscript protection for good(ss)
	15-Aug-94 (MDM) - Try to add some protection in the case when
			  the execution is interupted in the middle of
			  reading the SDC roadmaps
	29-Nov-94 (MDM) - Modified the logic so that the closest image
			  above and below the desired exposure duration
			  are used.  Previously, it used a short exposure
			  and a medium or long exposure no matter what the
			  input exposure duration was.
	30-Nov-94 (MDM) - Fairly large change to the technique used to find
			  a match.  It MUST be within +/- 30 days now, and 
			  it still minimizes the DPE error and temperature
			  error and finds the image closest in time with
			  those minimum error.	
	27-Feb-95 (MDM) - Modified to allow a large temperature error when
			  no SDW data is available.
	 1-Mar-95 (MDM) - Patched error which occured during warm CCD and
			  when /INTERPOLATE is used.
	15-May-95 (MDM) - Modified to be able to use PFI images as the
			  input (slight modification to the 288 line number
			  starting corner of FR images code).
       05-Feb-98 (TRM) - Modified definition of /short so that and equal
                         DPE does not match for the short case
          8-Feb-98 (SLF) - added a '/cd' to file_list call
                           (avoid no file found message when #files gets big
          5-Jan-99 (SLF) - fixed ancient y2k problem
         02-Dec-02 (TRM) - Change +/- 7 day search to +/- 10 day search
	30-Mar-04 (LWA) - Increased SDC max_temperr to 6 degrees for time prior
			to CCD cooling ('2-Oct-91 09:00').
			  Corrected error in 14-Nov-92 test logic.
			  Changed 2 intarr to lonarr to cope with SDC_06.

			  are used.  Previously, it used a short exposure
			  and a medium or long exposure no matter what the
			  input exposure duration was.
	30-Nov-94 (MDM) - Fairly large change to the technique used to find
			  a match.  It MUST be within +/- 30 days now, and 
			  it still minimizes the DPE error and temperature
			  error and finds the image closest in time with
			  those minimum error.	
	27-Feb-95 (MDM) - Modified to allow a large temperature error when
			  no SDW data is available.
	 1-Mar-95 (MDM) - Patched error which occured during warm CCD and
			  when /INTERPOLATE is used.
	15-May-95 (MDM) - Modified to be able to use PFI images as the
			  input (slight modification to the 288 line number
			  starting corner of FR images code).

    displayed in 1024x768 window.
    For data of which FOV is larger than that, 96x96 part
    is cut from each image and rebinned into 384x384. Then
    they are displayed in 1152x768 window.
    Space Craft jittering is corrected.

CALLING SEQUENCE
    sel_img,data,index
INPUTS
    data, index = that of taken by YODAT.

SET_MWLT $SSW/yohkoh/ucon/idl/wuelser/set_mwlt.pro
[Previous] [Next]
NAME:
       SET_MWLT
PURPOSE:
       Interactively define reference points in an image and a (full-sun)
       reference image.  These points can be used to calculate a linear
       transform which maps image a onto the (full-sun) reference image imb.

       This special version of SETPTS is used to co-align active region
       data with a full-sun image.  First, both images are desplayed at full
       size, and the user is asked to click the region of interest in the
       full sun image.  Then a partial image is used to enter the reference
       points.
       After the points have been entered, image ima is transformed and
       displayed with contours on top of image imb.
CATEGORY:
       Image processing.
CALLING SEQUENCE:
       set_mwlt,p,ima,imr
INPUTS:
       ima = image to be transformed.
       imr = (full-sun) reference image.
OPTIONAL (KEYWORD) INPUT PARAMETERS:
       subsize = integer.  Pixelsize of subimage to be used as reference.
                 Default = 100, corresponds to about 4 arcmin in new MWLT.
       plotonly = flag. If this keyword parameter is present, no new points
                  are added to p, but the result of the linear transform is
                  displayed.
       noscale = flag.  If present, the image is displayed unscaled.
       append = flag.  If present, new points are appended to p if p exists
                and contains points.  The default is to discard old points.
       key = transformation type.  See "transtype" keyword in CALTRANS for
             details.  Default is a general linear transform.
OUTPUTS:
       p = array(2,2,*). p(0,0,*) and p(1,0,*) are the x and y coordinates
           of the points in the reference image imb. p(0,1,*) and p(1,1,*)
           are the x and y cordinates of the same points in the image ima.
OPTIONAL (KEYWORD) OUTPUT PARAMETERS:
       trima = transformed version of ima
 CALLS: ***

 CALLED BY:
	sxt_prep [1], sxt_prep [2], sxt_prep [3]
OPTIONAL KEYWORD INPUT:
	reset	- Go back to using the old standard directory
METHOD:
	1. Create a file with the dark and leak images you wish
	   to use.  The prefix for the file MUST BE:
		sdc	- for dark images
		sfc	- for leak images
	   * There can be multiple files.  **ALL** files with that prefix
	     in that new directory are checked for the best match
	   * NONE of the standard dark or leak images are checked if
	     you use this new option (ie: you must have ALL of the dark
	     images you want in your off-line dark/leak image file).
	     Extract images from the standard SDC set and put them into
	     your off-line set if you need them
	2. Redirect the environment variables to point to your offline
	   area by calling SET_NEW_DB.  The routine deletes the common
	   block saved info so that it is re-built on the next DARK
	   or LEAK call.  This takes many seconds for the DARK calls
	   so swapping back and forth between official and off-line
	   databases will be very slow.
	3. Run SXT_PREP and/or LEAK_SUB and/or DARK_SUB
	4. To return to using the original official database, use the
	   /RESET option on the SET_NEW_DB command.  This assumes that
	   you had not done a SETENV outside of this routine.
EXAMPLE:
	The following is an example of how to use PFIs for the source
	dark frames.  CAUTION: If the ROI location on the CCD changes,
	the DARK_SUB routine will probably not choose the optimal
	pointing dark frame (it chooses the closest in TIME)

PRO xform, xi,yi,zi, xo,yo,zo, TRANSFORM=t, HELP=help

 Apply transformation set up by function set_xform.
 Keyword TRANSFORM supplies the transformation matrix, e.g.
   TRANSFORM=xf.helio2image.
 See set_xform for full documentation on the coordinate systems.
 Helio2image = heliographic to image-plane.
 Image2helio = image-plane to heliographic.
 These can be applied to coordinates, magnetic fields, velocities, ...
 Zimage2helio = image-plane xi,yi to heliographic xh,yh, with the point
 referred to by xi,yi understood to lie on the photosphere i.e. zh=0.
 The suppressed zi is nonzero. This transformation matrix is 2x2, whereas
 the others are 3x3.

 The following forms are accepted if TRANSFORM is helio2image or image2helio:
 xform,xyz		; replace the vector xyz=FLTARR(...,3)
			; by the transformed vector.
 xform,xyzi,xyzo	; transform the vector xyz=FLTARR(...,3) and return
			; the result in xyzo=FLTARR(...,3).
 xform,x,y,z		; replace the components x,y,z, which can be of arb.
			; dimensions, by the transformed components.
 xform,xi,yi,zi,xo,yo,zo ; transform the components xi,yi,zi, which can be
			; of arb. dimensions, and return the resulting
			; components in xo,yo,zo.

 The following forms are accepted if TRANSFORM is a zimage2helio matrix:
 xform,xy
 xform,xyi,xyo
 xform,x,y
 xform.xi,yi,xo,yo
 These are analogous to above, but the vectors are FLTARR(...,2).

FUNCTION set_xform, b0,p,bc,lc, HELP=help

 Calculate and store transformation between image-plane and heliographic
 coordinates and various other useful info. Tranformations are linear,
 assuming a tangent plane on the photosphere at the reference point.
 Thus the reference point should be the center of the FOV.

 INPUT:
	b0	solar sub-Earth latitude (radians)
	p	solar p-angle (radians)
	bc	latitude of reference point on photosphere (radians)
	lc	cmd of reference point on photosphere (radians)
 OUTPUT:
	xf	a structure containing the information --

 transformations --
 xf.helio2image	; Heliographic xh,yh,zh -> image-plane xi,yi,zi.
			; FLTARR(3,3).
 xf.image2helio	; Image-plane xi,yi,zi -> heliographic xh,yh,zh.
			; FLTARR(3,3).
 xf.zimage2helio	; Image-plane xi,yi -> heliographic xh,yh.
			; ASSUMING (the unobserved) zi is such that zh=0 i.e.
			; the observed image lies in the photospheric plane.
			; FLTARR(2,2).
 *NOTE*NOTE**NOTE*	These arrays are stored transposed so that "normal"
 *NOTE*NOTE**NOTE*	matrix arithmetic works as expected, e.g.
 *NOTE*NOTE**NOTE*		B_i = xf.helio2image # B_h
 *NOTE*NOTE**NOTE*	"PRINT,xf.helio2image" will print it transposed too.

 ; useful things to know --
 xf.b0			; Solar latitude of sub-Earth point (radians).
 xf.p			; Solar p-angle (radians).
 xf.bc			; Latitude of center of FOV (radians).
 xf.lc			; Cmd of center of FOV (radians).
 xf.DirCos		; Direction cosines of LOS relative to helio xh,yh,zh
 			; coordinate system in radians (FLTARR(3)).
 xf.mu			; Cos(angle from disk centre) in radians.
 xf.SolRad		; Solar radius in Mm (megametres).
 xf.Mm2arcsec		; Mm on photosphere -> arcsec at Sun.
 xf.Mm2radian		; Mm on photosphere -> radians of CMD or latitude.
 xf.arcsec2Mm		; Arcsec at Sun -> Mm on photosphere.
 xf.radian2Mm		; Radians of CMD or latitude -> Mm on photosphere.

 DEFINITION OF COORDINATE SYSTEMS:
 xh,yh,zh	Heliographic coordinates. zh is normal to the photosphere
 		(actually the tangent plane).  xh in Westerly (+ve CMD)
 		direction, yh in Northerly (+ve latitude) direction.
 xi,yi,zi	Position in image plane.  xi is terrestrial West, yi is
		terrestrial North.  zi is distance towards observer from
		the image plane, where the origin (xi=0,yi=0,zi=0) of
		the image plane touches the photosphere.
		Could be generalized for images not oriented to terrestrial
		North/West.

 It is not really necessary to store the 3 transformations in xf.
 helio2image and image2helio are inverses of each other; since the
 transformations are unitary? orthogonal? or something one is just
 the transpose of the other. Also, zimage2helio can be bypassed by
 computing the zi needed to make zh=0, given xi, yi, and image2helio,
 then using these xi,yi,zi to compute xh,yh,zh given image2helio.
 However, they are stored for generality.
 Clearly there is duplication among the constants too, specifically
 radian2Mm == SolRad == 1/Mm2radian. and arcsec2Mm = 1/Mm2arcsec.

 USAGE EXAMPLES:

 ; Get heliographic coordinates of observation points (pixels) on photosphere
 ; in Mm given pixel positions in arcsec.
 xyzh=FLTARR(Nx,Ny,3) & FOR i=0,Nx-1 DO FOR j=0,Ny-1 DO $
	xyzh(i,j,0:1) =  xf.arcsec2Mm * xf.zimage2helio # [xi(i,j),yi(i,j)]

 ; Compute noise on Bx assuming 15G error in LOS field and 150G error

SETPTS [2] $SSW/yohkoh/gen/idl/gbo/setpts.pro
[Previous] [Next]
NAME:
       SETPTS
PURPOSE:
       Interactively define reference points in two images.
       These points can be used to calculate a linear transform which maps
       image ima onto the comparison image imb.
       After the points have been entered, image ima is transformed and
       displayed with contours on top of image imb.
CATEGORY:
       Image processing.
CALLING SEQUENCE:
       setpts, p, ima, imr
INPUTS:
       ima = image to be transformed.
       imr = reference image.
             Usually, the lower resolution image is selected to be image ima.
OPTIONAL (KEYWORD) INPUT PARAMETERS:
       plotonly = flag. If this keyword parameter is present, no new points
                  are added to p, but the result of the linear transform is
                  displayed.
       noscale = flag.  If present, the images are displayed unscaled.
       append = flag.  If present, new points are appended to p if p exists
                and contains points.  The default is to discard old points.
       trima = transformed image ima.
       key = transformation type.  See "transtype" keyword in CALTRANS for
             details.  Default is a general linear transform.
OUTPUTS:
       p = array(2,2,*). p(0,0,*) and p(1,0,*) are the x and y coordinates
           of the points in the reference image imb. p(0,1,*) and p(1,1,*)
           are the x and y cordinates of the same points in the image ima.
OPTIONAL (KEYWORD) OUTPUT PARAMETERS:
       trima = transformed version of ima

       After entering the procedure, follow the instructions printed
       on the terminal.
RESTRICTIONS:
       The images have to be 2-dimensional. If one of the images is bigger
       than 512x512 pixels, only a part of the image can be displayed, and
       used to set points.

 INPUTS:
   image	- image array to clean (may be 2-d or 3-d)
   threshold 	- sets the threshold level for which all
		  spikes are removed.  Suggest using a value
		  of 10.  Really bright or dark spikes can be

 OPTIONAL KEYWORD INPUT:
   width	- set the width of the median filter (3 is default)
   average	- use average filter instead of median.
   pos		- remove spikes only.
   neg		- remove holes only. Note: threhold must be less than 0.

 RETURNED:
   cleaned image with the same size and data-type as input image
 OPTIONAL KEYWORD OUTPUT:
   indices	- list of indices to the located spikes and dark holes.
 PROCEDURE:
   This routine calls the idl function SPIKES.  
   The spikes and dark holes are identified via the following method:

     spike_indices = where(abs(image-median(image,width)) gt threshold)

     If neg is used than:
     spike_indices = where((image-median(image,width)) lt threshold)

 MODIFICATION HISTORY: 
   12-Jan-94, GAL, Written (replaced LWA's spikes_off routine)
   16-17 Mar-94, GAL, added code to handle decompressed images.
	added keywords to use upgraded version of spikes.
   11-April-94, gal, modified to preserve input data-type
   14-Apr-94, gal, modified to only sfd compress/decomp filter 
		spike/hole data for non-byte input.  The comp/decomp
		introduces about a 1% error to the filtered spike/hole
		data.
   20-Apr-94, gal, modified to only use sfd compression for finding
		spikes/holes in non-byte type data via spikes rountine.  
		The filter values used for replacement are not compressed 
		and are always generated via filter function.
   11-Dec-94, LWA, made from de-spiker by removing image compression.
   11-nov-96, SLF, changed call to <filter> to <image_filterer>

 OPTIONAL KEYWORD OUTPUTS:
	N_CHANGE = # of pixels changed (replaced with neighborhood mean).
	VARIANCE = image of pixel neighborhood variances * (N_sigma)^2,
	DEVIATION = image of pixel deviations from neighborhood means, squared.
 PROGRAMS CALLED:
	big_smooth
 PROCEDURE:
	Compute mean over moving box-cars using smooth, subtract center values,
	compute variance using smooth on deviations from mean,
	check where pixel deviation from mean is within variance of box,
	replace those pixels in smoothed image (mean) with orignal values,
	return the resulting partial mean image.

 METHOD: Take the pixel coordinates of the on disk points, map them 
	  to heliocentric coordinates, add the appropriate differential 
	  rotation, and map them back. 
	  All pixels that have rotated behind the limb are marked by [-1,-1]
	  entries. For now just take longitude to +/- 90.

			same size pixels as the image.
		date 	the time of the image, in standard 7 part form, 
			[DD-MMM-YY HH:MM:SS].
		delt	the rotation time, in decimal days.
		out     the return is a 2xn matrix with the new x & y pixel 
			coordinates.

[Previous] [Next]
       NAME: spike_1d_id

       PURPOSE: To locate single element spikes in 1-D arrays.

       METHOD: Default uses a boxcar smoothing filter as a 
		reference, takes the difference and compares it with the
		cutoff value. The returned variable is a vector of pointers 
		to spikes (both - and +) in the input variable.
		  [Unless "pos" or "neg" are set.]
	    -- For many applications it is best to use ALOG(ARRAY)
	       so that the search is done as a change in a
	       multiplicative factor rather than an additive term.

       CALLING SEQUENCE:
		out = spike_1d_id(array,cutoff,[remove=remove,width=width])

spikes [2] $SSW/yohkoh/gen/idl/util/spikes.pro
[Previous] [Next]
       NAME: spikes

       PURPOSE: To locate single pixel spikes, like Cosmic Rays,
		 in 2-D images.

       METHOD: Default uses a three point median  filter as a 
		reference, takes the difference and compares it with the
		cutoff value. The returned variable is a vector of pointers 
		to spikes in the input variable.  Default mode is to remove
		holes and spikes.  Average filter is also available.

       CALLING SEQUENCE:  spikes=(img,cutoff,[remove=remove,width=width,
				average=average, pos=pos, neg=neg])


       PARAMETERS: 	img		input image 
			cutoff		comparison cutoff 

	KEYWORDS:	/remove		when set return corrected 
					image
			width		median filter size (default
					is 3).
			/average	use an average filter instead
					of median.
			/pos		remove only spikes (or bright val)
			/neg		remove only holes (or dark values)
 CALLED BY:
	NAME [3], de_spiker [1], de_spiker [2], despike, sfc_de_spiker, wl_process

spikes_off $SSW/yohkoh/ucon/idl/acton/spikes_off.pro
[Previous] [Next]
 NAME:
  spikes_off

 PURPOSE:
  Remove spikes and streaks (e.g., SAA, dark spikes) in a data array.

 CALLING SEQUENCE:
  spikes_off,data,level,out [,ups,downs,neg=neg,both=both,width=width]
  spikes_off,data,25,clean_array -- removes positive spikes only
  spikes_off,data,7,clean_array,/neg -- removes negative spikes only
  spikes_off,data,10,clean_array,ups,downs,/both -- removes 
     both + and - spikes and returns spike ID array of both types

 INPUTS:
  data = image or image cube of any type
  level = amplitude of spike to be removed
	(try 10 to start and move up or down by experiment)

 OPTIONAL INPUT KEYWORDS:
  neg, set this keyword to remove negative spikes from 
	dark frame subtraction, etc.
  both, set this keyword to remove both + and - spikes to
       amplitude set by level.
  width, width of smoothing in call to median, default = 3

 OUTPUTS:
  clean_array = the data array cleaned of spikes.
  ups = the ID array of the location of positive spikes
  downs = the ID array of the location of negative spikes

 ADVICE
  I have found that it is sometimes necessary to put the data through the
  	program 2 or 3 times to achieve maximum cleaning.
  For single SXT images, level = 7 is a reasonable value.
  For composite images with their greater dynamic range try 25.
  A good check on whether real data are being affected is to do the
	following test:
		test = original_image - clean_image
		tvscl,test
	If the pattern of pixels in the test image does not reflect any of
	the structure of the solar image it is safe to assume the cleaning 
	is OK.
  It is also useful to ask for the ups and downs in the call and do
               test = bytarr(xs,ys) where xs and ys are the dimensions
			of one of the images in your array.
               test(downs) = 1
               test(ups)   = 2
               tvscl, test
  This shows which pixels were modified in the last image processed

   October-93, LWA, added keyword "both"
   March-94, LWA, added feature to do spike ID on SFD_COMPRESSED image
	if a non_byte image is passed in.  Also had to create
	spike_id.pro and call it in order to keep the ups/downs/both 
	feature of my program.  Changed the program to a procedure
	and added the ability to return the spike ID arrays.
   3/9/94 put "NO SPIKES" messages outside of loop.  LWA

  PROCEDURE
	One day of data are read in according to keyword
	input.  A log scaled 1024x512 data cube,
	with Terms on the left and Syns on the right, is prepared.  
	Initially, all stepper2 output flags are set to 0 which
	means SynSFCs are selected.  However, if keyword(term) has
	been set the flag indices are all set to 1 as it is
	anticipated that most images will use TermSFCs as will
	be the case, e.g., for leak epochs 1 and 2.
	A small AlMg image is displayed in the upper RH corner
	for comparison purposes.

	Selection flags can be toggled in the stepper2.pro fashion.  
	After the selection process is complete an sda data
	file is written from the Term and Syn selections
	combined.  The saved AlMg selections are always SynSFCs.

sswhere $SSW/yohkoh/sxt/idl/util/sswhere.pro
[Previous] [Next]
 NAME:
       sswhere 

 PURPOSE:
	To produce an SS string for use with YODATroutine.
       Given a roadmap or index of many frames you can select
       a narrower subset. 
       When using index remember that the returned string 
       contains indices into the limited set defined by index,
       NOT the full set defined by roadmap.
          
 CALLING SEQUENCE:
 	ss=sswhere(roadmap)

       or

 	sr=sswhere(index) then ss=ss(sr)
        

 METHOD/OPERATION:

	This routine opens a widget. There is are sliders to set
       the minimum frame percentage and the maximum amount of 
	saturation, and buttons to select the image parameters. 
	The logic is OR within categories, and AND between categories, 
	except for the filters, where you can choose either AND or OR 
	logic, with OR being the default (unless there is only one 
	A filter or one B filter). If you choose AND then you must 
	select a filter in both the A & B lists obtaining frames with 
	that combination of filters. If you choose OR logic you get
	all frames with any of the selected filters, thus you
	only need to select a filter in A or B (if you do both 
	you get all frames with EITHER filter).

       When you have finished setting the buttons, press
       'Test' and you can see how many images match the parameters
       you have selected. Pressing 'Select' will add the currently
       selected images to a cumulative total SS string. You can choose 
       multiple sets of parameters, and the resulting SS strings are
       OR'd together, while the text widget informs you of the total
       images selected so far. Whenever you are done press 'Exit'. 
       If you want to start over press 'Clear'.
       By popular request an 'All' button has been added to the DPE
       list, which sets all the DPE values at once (either on or off).
       Selection of any single DPE value resets this button. 

       You can also call either PLOT_FOV to select the field of view
	or SHOW_OBS3 for selecting the time range. You DO NOT have to
	do either, if you do then these selections are added to the 
	rest of the criterion to give a result. This can be seen with 'test'.
	Each routine has its own CLEAR button which undoes any current
	selection, returning to the default (everything). The general 
	clear button also resets these.           

  	NB: The handling of the image percentage is done with direct
	access to the input structure (in mk_mask) rather than through
	one of the "gt_" routines.

 KEYWORDS:	ar	when set allows post-widget selection of data 
			from a specific active region

		widget blocking is the problem and since blocking was introduced
		in IDL 5.0, /block is now added to xloadct when

STR_FILL $SSW/yohkoh/ucon/idl/metcalf/str_fill.pro
[Previous] [Next]
NAME:
     STR_FILL
PURPOSE:
     Fill a structure from a data array or another structure - simulates an 
     equivalence stetement for structures.

     The structure is filled byte by byte from the data array.  If the array
     is longer (in bytes) than the structure, the first part of the array 
     is used.  If the array is too short, as much of the structure as 
     possible is filled.
CATEGORY:
CALLING SEQUENCE:
     bytes = str_fill(structure,array,index=index,tags=tags)
INPUTS:
     structure = the structure to be filled
     array = the array of data to use in filling the structure (can be 
             another structure).  Can be of any type.
OPTIONAL INPUT PARAMETERS:
     index = If the structure to be filled is an array of structures,
             setting index fills only specific structure elements of the 
             array of structures.  Index gives the element number(s).  This 
             is necessary since IDL passes an element of a structure array by
             value, not by address.  Hence passing strucure(index) to 
             str_fill will not fill the structure array element.  The entire 
             array must always be passed.  Hence to fill an array element, 
             pass the entire structure and specify the index keyword.  Index 
             can be a vector of indices.  Default = all elements of the array.
     tags = The same problem crops up if you only want to fill certain tags
            in the structure.  The tags input is a vector of tag numbers to 
            be filled.  The others are left alone.  Default = All tags.
KEYWORD PARAMETERS
     /check = Check that the array has at least enough data to fill the 
             structure.
     /exact = Check that the array will EXACTLY fill the structure.
     /printable = force strings to be composed of printable characters
                  only (32b to 126b).
OUTPUTS:
     The input structure is modified (filled).
     bytes = the number of BYTES from array put into the structure
 CALLS: ***
	STR2BYTARR
COMMON BLOCKS:
SIDE EFFECTS:
     The input structure is filled
RESTRICTIONS:
     The number of bytes in each data type is hardwired to:
        nbytes = [0,1,2,4,4,8,8,1,1]
PROCEDURE:
EXAMPLES:
     To load a structure from a byte array:
     IDL> c={a:0,b:0}
     IDL> print,str_fill(c,[0b,1b,0b,2b])
           4
     IDL> help,c,/str
     ** Structure <1daf88>, 2 tags, length=4, refs=1:
        A               INT              1
        B               INT              2

     To determine the byte size of a structure:
     IDL> print,str_fill(c,c,/nocheck)
                4

     To fill a few elements of an array of structures:
     IDL> c={a:0,b:0}
     IDL> c=replicate(c,4)
     IDL> a={a:5,b:5}
     IDL> print,str_fill(c,replicate(a,2),index=[1,2])
                8
     IDL> print,c
     {       0       0}{       5       5}{       5       5}{       0       0}

MODIFICATION HISTORY:
     T. Metcalf November 1992
     T. Metcalf December 1992 Fixed the string code so that 0b is never
                              output to a string (this fouls things up
                              since 0b is the end-of-string marker.  If
                              /printable is set 0b through 31b becomes a 
                              space.  If /printable is not set, 0b becomes 1b.


STR_LOAD $SSW/yohkoh/ucon/idl/metcalf/str_load.pro
[Previous] [Next]
NAME:
     STR_LOAD
PURPOSE:
     Load a strucutre from an identical sturcture (same definition of tags).
     You would think you can just type "a=b" in IDL, but if the structure
     names are different, you will get an error, even if the structures
     are identical.  This routine gets around this problem byt loading the
     structure tags one at a time.
CALLING SEQUENCE:
     str_load, filee, filler
INPUTS:
     filler = the structure from which data is taken
KEYWORD INPUT:
     index = if the fillee structure is an array of structures and you only
             want to fill some elements of the array, set index equal to the
             the array indices to be filled.  You can't simply pass something
             like fillee(index) in the call to str_load because IDL will pass
             fillee(index) by value rather than by reference.
     tags = if you want to fill just a few tags in the structure, pass 
            a vector of tag index numbers in tags.  Applies to both fillee
            and filler.
OUTPUTS:
     fillee = the structure to be filled.  It must have the same definition
              as filler.

 PURPOSE:
   To examine sunset images and select good ones.
 CALLING SEQUENCE:
   sunsets,data,info_array,sx=[2,3]
 INPUTS:
   data   = SXT data cube, all images of same exposure.
   info_array = the usual produced by get_info2(index) or yodat
   sx = index array of pairs of sunlight and sunset images where the
       sunlight images come first, e.g.,
       sx=[1,2,3,4,10,9,10,11,12,13,17,18]
 OUTPUTS:
   First the sunset image is displayed with a pause, no tv scaling is done
   Then the normal image is displayed with a pause, no tv scaling is done
   Then the difference of the (sum of lines 10:15)/6 is presented
  INTERPRETATION
       No x-ray features and scatter around 0 = good sunset image
       Largely positive values = sunset image too late (faint)
       Negative values = poor choice of sunlight image, try again.

  NOTE -- the following is to remind me how to select sunset images.

sxl_analysis $SSW/yohkoh/ucon/idl/acton/sxl_analysis.pro
[Previous] [Next]
       NAME: sxl_analysis


       PURPOSE: Collect data from the SXL data base for study of the
		radiative output of the corona within different brightness
		regimes versus time.  Basic input data are the SXL 
		histograms.  Output data are total decompressed DN/HRpix/sec.
		The normalization to /sec comes from the fact that the 
		SFDs are normalized this way. 
	COMMENTS - (3/10/96):
                Changed the conversion to throw away sxl(dn)=0
		to compensate error introduced by mk_sfd ignoring
		negative values after dark/leak subtraction.  Kept integer
		truncation of sfd_decomp as this gave a more accurate
		result for the 1 case (25-May-95) tested.
		 However, for the on-disk fluxes between levels I have
		kept the sxl(dn)=0 in the sum because the on-disk intensities
		are more likely to be above background.

OPTIONAL KEYWORD INPUT:
	hxa	- If set, use HXA_SUNCENTER.  Default is to use GET_SUNCENTER
	cmd	- If set, use the S/C commanded pointing data file.  The true
		  suncenter can be up to 4-5 pixels different because of the
		  "slop" in the attitude control.  Default is to use 
		  GET_SUNCENTER
	oride_pnt_chk - If set, then do not compare the ATT/GET_SUNCENTER
		  results to the commanded values to see that they are
		  truly valid points.  This is useful for times when the
		  commanded pointing history file is not updated properly
		  or for real time applications when the commanded pointing
		  history is not updated yet.
       rawcmd -  if set, use commanded and do not apply seasonal correction
OPTIONAL KEYWORD OUTPUT:
	delta	- Time difference (in s) between index time and pnt
                 time for each sun center position.  A value larger than a few
                 seconds indicates that the suncenter position may not be
                 reliable.  It is only valid when not using /HXA or /CMD
		  options.
	roll	- The SXT roll in degrees.  The CCD-north is "roll" degrees
		  counter clock wise from solar-N.
	att_ok  - Indices of those pointings which have ATT files within 1 second
		  of times and which have perfect (att.status1=4) HXA solutions.
METHOD:
	This routine is intended as a front end to return the pointing 
	information.  It does a check to see that the PNT files exist 
	when using GET_SUNCENTER or HXA_SUNCENTER.

       The seasonal/mission long drift correction can be disabled
       the the IDL command: setenv,'ys_no_attcmd_corr=1'
HISTORY:
	Written 10-Jun-93 by M.Morrison
	10-Jul-93 (MDM) - Check that the value to be returned is believable
			  and if not, use the /CMD option for the bad values.
	14-Jul-93 (MDM) - Replaced some code with a call to PNT_EXIST
	18-Aug-93 (MDM) - Replaced PNT_EXIST call with YDB_EXIST
			- Replaced call to GET_SUNCENTER with a call to
			  GET_ATT if the ATT files exist
	19-Aug-93 (MDM) - Added DELTA variable
	17-Sep-93 (MDM) - Added ROLL keyword output
			  Introduced code to call GET_ROLL
	 2-Oct-93 (MDM) - Corrected error where a problem arises when some
			  of the ATT files exist, but not the one needed.
	16-Oct-93 (MDM) - Make sure that the roll variable is defined 
	19-Nov-93 (MDM) - Added "min_status=2" call to GET_ATT so that the
			  results returned are at least acceptably good
	11-Jan-94 (MDM) - Modified not to display "values returned are
			  unreasonable" message if /CMD is set.
	10-Feb-94 (MDM) - Modified the criteria that is used to recognize bad
			  results in the ATT database to use the relative
			  offset from commanded IN ADDITION to the absolute value
			  of "lt 100 or gt 900".  If x or y is more than 50
			  pixels from expected, and outside the above range, then 
			  it is flagged as bad and the expected (commanded value) 
			  is used.
	21-Feb-94 (MDM) - Added /ORIDE_PNT_CHK to optionally not compare the 
			  ATT/GET_SUNCENTER results to the commanded values to see 
			  that they are truly valid points
	21-Feb-94 (MDM) - Added capability of setting /ORIDE_PNT_CHK by setting
			  and environment variable "YS_ORIDE_PNT_CHK" to non-null
	29-Nov-94 (MDM) - Print warning statement if the ATT record that it selects
			  is over 5 minutes from the requested time.
	14-Feb-95 (MDM) - Changed warning message to say ATR instead of PNT
        9-Mar-95 (MDM) - Modified SXT_CMD_PNT to apply the correction required for
                         the seasonal/mission long drift between the
                         commanded and actual.
       25-mar-95 (SLF) - add RAWCMD keyword and function
	15-sep-98 (LWA) - added att_perfect as an option keyword output.
	21-sep-98 (LWA) - corrected min_status bug introduced on 15-sep-98.
       23-May-99 (NN)  - included in the ATT mismatch warning the time of interest
                        and the closet ATT time.
        8-Jun-99 (NN)  - fixed the bug that resulted from the 23-May-99 change.
