NAME:
  astrepro
 PURPOSE:
  Re-reduce existing astrometry originally measured with ASTROM
 DESCRIPTION:
  This file attempts to rereduce astrometric measurements in the current
    directory.  These measures are x,y positions that are found in the
    file, position.dat.  The files fitcoeff.dat and centers.dat are
    scanned for the corresponding transformation relations between x,y
    and RA,DEC.  Any object.ast files in this directory will be overwritten.

 CATEGORY:
  Astrometry
 CALLING SEQUENCE:
