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.
