AXIS /UNIT

###
AXIS /UNIT

        The option /UNIT is used to convert the axis coordinates to the  desired
        unit,  M  for arc minutes, S for arc seconds, R for Radians. This option
        is valid only if a PROJECTION and a SYSTEM (EQUATORIAL or GALACTIC)  are
        both  defined.  See HELP TICKSPACE for more information on how to master
        the Tick spacing with the /ABSOLUTE or the /UNIT options.
