SET ANGLE_UNIT

            [DISPLAY\]SET ANGLE_UNIT [Degree|Minute|Second|Radian|ABSOLUTE|RELA-
        TIVE]

        List  or  Specify the angular unit and mode used for box labelling.  The
        mode can be ABSOLUTE to use sexagesimal notation in Hour  -  Degree  for
        Right  Ascension  and  Declination, or RELATIVE to label with offsets in
        the current angle unit.

        SET ANGLE_UNIT
        will list the current and fallback units (if any)

        SET ANGLE_UNIT ABSOLUTE|RELATIVE
        will toggle between ABSOLUTE labels and relative ones in the current an-
        gular unit. ABSOLUTE labeling is not possible if there is a rotation an-
        gle in the images: only relative labels are used in this case,  whatever
        the mode specified by SET ANGLE_UNIT.

        SET ANGLE_UNIT Degree|Minute|Second|Radian
        will  set the current angle unit to the specified value, and enforce use
        of offset labels in the specified unit.
