[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.
