HELP SECTION

COODEFINE
Type: Verb
Use:  COODEFINE is used to alter the celestial axis descriptions in
      the catalogue map header.
Adverbs:
  INNAME......Image name(name).       Standard defaults.
  INCLASS.....Image name(class).      Standard defaults.
  INSEQ.......Image name(seq. #).     0 => highest.
  INDISK......Disk drive # of image.  0 => any
  COORDINA....The X and Y coordinates are found as:
              Xpos = abs(CO(1)) + abs(CO(2))/60 + abs(CO(3))/3600
                 if any of CO(1), CO(2), CO(3) < 0: Xpos = -Xpos
              Ypos = abs(CO(4)) + abs(CO(5))/60 + abs(CO(6))/3600
                 if any of CO(4), CO(5), CO(6) < 0: Ypos = -Ypos
              These are used here for RA, Dec (or other celestial
              systems such a GLON/GLAT) in sexagesimal notation.  The
              units are degrees, minutes and seconds of arc except for
              RA in which they are hours, minutes, and seconds of time.
  COOINC......Axis increment to set (RA/Dec). 0 => no change.
              Units are arc seconds.  Be careful of sign.
  COOREF......Reference pixel location (Ra/Dec).  If both are 0
              exactly, then no change is made.
  ROTATE......Coordinate rotation of the celestial coordinates from
              the axis coordinates in degrees.  < -180 => no change.
