NAME
astrom - determines World Coordinate System coordinates
SYNOPSIS
astrom coord_list [debug] [crpix1=] [crpix2=] [mirror] [residuals]
DESCRIPTION
Use astrom determines the astrometric conversion between
the rows and columns in an image and the RA and Dec of the stars.
The program compares two lists, the starlist or row/columns
which comes in standard input and the coordinate list which
must be the first argument.
Both lists must have the same number of members and be collated.
When successful it prints out a line like:
ra=286.0561 dec=33.2469 equinox=2000.000 scale=0.007470 rot=-93.3722 rms=2.2 crpix1=22.0 crpix2=34.0
Where the ra and dec are for the crpix1,crpix1.
The scale is in degrees per pixel.
The rotation angle in degree (+/- 180).
The rms in arc-seconds.
OPTIONS
crpix1 - sets the CRPIX1 value (center column).
crpix2 - sets the CRPIX2 value (center row).
mirror - sets the determininant to be -1.
Not Ready.
residuals - prints out row,col residuals from fit.
