          (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.
