[ADVANCED\]MAP_POLAR GenericBegin [GenericEnd] /BACKGROUND Type [Min
Max] [/STEP Step Xfirst Yfirst]
Show the polarization vectors derived from the Polarization Angle and
Fraction maps overlaid on a background image.
Type can be I for total intensity, F for fractional polarization in per-
cent, or P for the polarized intensity. Min and Max indicate the SCALE
to be used for the color scaling (through a temporary assignments of the
SCALE values for SHOW command called by MAP_POLAR).
Type, Min, and Max, like Step, Xfirst, Yfirst are "sticky" (remanent):
they keep the previous value until a new one is specified, or are reset
to their default values by use of the /COMPUTE option. Default is I for
Type, 0 for Min and Max, which implies an automatic scaling to the data
range.
