NAME

offsetcoord - offset a celestial coordinate pair (ASCA)


USAGE

          offsetcoord fitsfile+ext ra dec

DESCRIPTION

To offset the CRVAL keywords in a FITS image:

       Usage: offsetcoord fitsfile+ext ra_off dec_off 

or

     To offset a coordinate pair, and write result to the screen:
     
       Usage: offsetcoord ra_old dec_old ra_off dec_off 
     
         where, "ra_off/dec_off" are RA/DEC offsets in arcmins,
           and, "ra_old/dec_old" are RA/DEC in degrees.

The offsets are simply added (i.e., ra_new = ra_old + offset / 60.0)
