[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.
