MAP_POLAR

    [/BACKGROUND Type Min Max] [/STEP Step Xfirst Yfirst] [/ANGLE Atype]

    Derive  or  Display the Polarization fraction and Polarization angles images
    from the (I,Q,U) Stokes images.

    GenericBegin indicates the file name prefix,  and  GenericEnd  the  filename
    postfix,  including extension. The Stokes I (resp. Q, U) image is assumed to
    be in 'GenericName'"-I"'GenericEnd'(resp. -Q and -U) The Polarization  frac-
    tion  image  will be called 'GenericBegin'"-P"'GenericEnd', while the Polar-
    ization angle image is 'GenericBegin'"-A"'GenericEnd".

    The default end  is  ".lmv-clean".  However,  when  using  with  the  Imager
    PIPELINE,  continuum images are in derived from the UV Table names by adding
    +C before the file extension, so GenericEnd should be "+C.lmv-clean".

        MAP_POLAR ?
    will simply display the current values of the "sticky" control parameters.
