            [ADVANCED\]MAP_POLAR  GenericBegin  [GenericEnd]  [/COMPUTE [Thresh-
        old]]

        Compute the Polarization Fraction image  'GenericBegin'"-P"'.Type',  and
        the  Polarization  Angle  image  'GenericBegin'"-A"'GenericEnd" from the
        'GenericName'"-K"'GenericEnd' images where -K is all of the -I, -Q,  and
        -U Stokes images.

        The  derivation  is only made on pixels that are brighter than Threshold
        sigma in the Stokes I image. The use of the /COMPUTE  option  reset  all
        parameters that control further display to their default values.
