; NAME:
;	smei_star_enough_bins
; PURPOSE:
;	Used in smei_star_fit.pro to test whether the lsq fit
;	for a star needs to be executed or not.
; CATEGORY:
;	ucsd/camera/idl/stars
; CALLING SEQUENCE:
	FUNCTION smei_star_enough_bins, 	  $
		fit_bkgnd						, $
		n_fitpsf						, $
		n_bkgnd 						, $ 
		min_psf_bins	= min_psf_bins	, $
		min_bkgnd_bins	= min_bkgnd_bins
; INPUTS:
;	fit_bkgnd	scalar; type: integer
;					0: background and PSF fitted simultaneously
;					1: background fitted simultaneously from PSF
;	n_fitpsf	scalar; type: integer
;					number of sky bins in PSF
;	n_bkgnd		scalar; type:integer
;					number of sky bins in background area
;					(only relevant if fit_bkgnd=1)
; OPTIONAL INPUT PARAMETERS:
;	min_psf_bins   = min_psf_bins
;				scalar; type: integer; default: 25
;					lower limit on number of sky bins in PSF needed
;					for lsq fit to proceed
;	min_bkgnd_bins = min_bkgnd_bins
;				scalar; type: integer; default: 5
;					lower limit on number of background bin needed
;					for lsq fit to proceed
; OUTPUTS:
;	result		scalar; type: integer
;					0: do not do lsq fit
;					1: proceed with lsq fit
; INCLUDE:
	@compile_opt.pro		; On error, return to caller
