[BUNDLES\]SPECTRAL_CLEAN DUAL NSmooth
In DUAL mode, SPECTRAL_CLEAN cleans a (spectrally) smoothed version of
the data cube, and the difference between this smooth version and the
original ones. The two Clean component tables are then merged to restore
the final image using UV_RESTORE.
NSmooth is the number of channels being smoothed together.
The DUAL methods involves Cleaning two data cubes, so is a somewhat
slower than a simple CLEAN. SPCLEAN%MEMORY indicates whether intermedi-
ate results are kept in memory (faster) or on temporary files (slower,
but allowing to work on larger files).
Mode MULTI should in general be preferred, but does not include the fi-
nal UV_RESTORE.
