MAP_POLAR /STEP

        [ADVANCED\]MAP_POLAR GenericBegin [GenericEnd] [/BACKGROUND Type Min
    Max] /STEP Step [Xfirst Yfirst]

    Specify the Step in pixels between adjacent display of polarization vec-
    tors. If not specified, or if 0, Step is empirically  derived  from  the
    angular resolution.

    Xfirst and Yfirst indicate the starting pixel along the X and Y axis re-
    spectively, allowing a controlled centering of the  vector  distribution
    on the background image.

    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 0 for
    Step, 1 for Xfirst and Yfirst.
