CLEAN [FirstPlane [LastPlane]] [/FLUX [Fmin Fmax]] [/RESTART [File]] with METHOD = CLEAN The simplest CLEAN algorithm, originally developed by Hogbom. In mosaic mode (See command MOSAIC), a mosaic clean is performed. Rings and or stripes may appear on extended sources. It is slower than CLARK for a single field but maybe faster for a mosaic. It is extremely robust. Cleaning can be inter- rupted by pressing C at any time.
