This software package is a collection of routines written in IDL
(Interactive Data Language, Research Systems Inc.) which compute
coronal and heliospheric magnetic fields. The package can handle
the horizontal current-current sheet-source surface model computations. 
The package is still under testing and the routine is not yet
versatile enough for general use.

In case you want to use this package, you are requested to follow the
conditions described below.

(1) When you prepare a manuscript which includes computational results
obtained by using this package, you are requested to refer to the following
article:
X. P. Zhao and J. T. Hoeksema, Prediction of the interplanetary magnetic
field strength, J. Geophys. Res., 100, 19, 1995,
and the usage of the routines has to be acknowledged in the paper.

(2) When your article is printed, you are requested to send its copy
to me.

(3) You can transfer this code to anyone working in the field of solar
physics, with the condition that this credit notice is also transferred
and is honored.

(4) If you find bugs or points that might improve the routines, please send 
such report to me.
