- * Module:	platepos.c (Plate solution WCS conversion
- * Purpose:	Compute WCS from plate fit
- * Subroutine:	platepos() converts from pixel location to RA,Dec 
- * Subroutine:	platepix() converts from RA,Dec to pixel location   
-
-    These functions are based on the astrmcal.c portion of GETIMAGE by
-    J. Doggett and the documentation distributed with the Digital Sky Survey.
