KEPLER /MASK

        [BUNDLES\]KEPLER /MASK [File [Threshold]] [/VSYSTEM Value]  [/VELOC-
    ITY R function(R)]

      (Experimental)

      Generate an approximate spatial mask for further use, e.g. in CLEAN or
    other masking operations. The brightness is assumed to decrease with ra-
    dius,  and a local line width of 0.3 km/s is assumed to derive the chan-
    nel-dependent mask. Convolution by the current Clean beam is performed.

      If a File argument is present, the resulting mask data cube is  stored
    in File (with default extension

      If present, Threshold (in range [0,1]) indicates that pixels below the
    apparent peak brightness times the Threshold should be out of  the  mask
    (i.e. have a value 0), the others in the mask (a value 1).

      If  Threshold  is not present, the mask values are just taken "as is",
    without being re-mapped to a 0,1 mask. A simple SIC formula can be  used
    to convert them to a 0,1 mask later.
