CLEAN ideas

The family of CLEAN algorithms is based on the a priori assumption that the sky intensity distribution is a collection of point sources. The algorithms have three main steps

Iterative search
for point sources on the residual map. As those point sources are found,
of the clean map 1) by convolution of the clean component list with the clean beam, i.e. a Gaussian whose size matches the synthesized beam size and 2) by addition of the residual map.
