        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.
