    with METHOD = CLARK

    A Major-Minor cycles CLEAN method, originally developed by B.Clark, in which
    clean components are selected using a limited beam  patch,  and  deconvolved
    through  Fourier  transform at each major cycle. In mosaic mode (See command
    MOSAIC), a mosaic clean is performed. Rings and/or stripes may appear on ex-
    tended sources.  Faster than the HOGBOM method for single fields  but  maybe
    slower  for  mosaics.  The  strategy to search for CLEAN components in CLARK
    method does not work properly when the secondary side lobes  are  too  large
    (e.g. larger than 0.3), or in case of high phase noise.
