20.6 MAP_POLAR

[ADVANCED\]MAP_POLAR [GenericBegin [GenericEnd]] [/COMPUTE [Threshold]] [/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 fraction image will be called 'GenericBegin'"-P"'GenericEnd', while the Polarization 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.
