with METHOD = SDI
Perform a Steer-Dewdney-Ito CLEAN. This clean method selects an ensemble
of clean components and remove them at once using FFTs. It works best
for extended sources and UV coverages with short spacings. In such a
case, it may avoid the "ringing" features which appear using the CLARK
or HOGBOM techniques. In mosaic mode (see command MOSAIC), a mosaic
clean is performed.
SDI is very sensitive to the selected support (see MASK and SUPPORT com-
mands), especially when the dirty beam sidelobes are significant.
