Next: BOX /BRIEF
The option /ABSOLUTE is used to write (RA,DEC) labels for EQUATORIAL
system or (L,B) coordinates for GALACTIC system when a projection is ac-
tive, i.e., both a PROJECTION and a SYSTEM are defined. RA (or L) is
used for X-like axis, and DEC (or B) for Y-like axis. Note that this
should be used only for small fields (size less than 0.2 Radians), and
must be used only with the axes at the default position (i.e. no /LOCA-
TION option). When SYSTEM is defined but the projection is NONE or has
never been defined, the /ABSOLUTE option supports large fields (since
PROJECTION NONE makes a non-conformal mapping anyway). The SET SEXAGESI-
MAL command (see help) permits some mastering on how UNKNOWN or GALACTIC
ABSOLUTE labels are written.
See HELP TICKSPACE for more information on how to master the Tick spac-
ing with the /ABSOLUTE or the /UNIT options.
