    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.
