### Comparison of deconvolution algorithms

`HOGBOM` is the basic `CLEAN` algorithm. It is robust but slow. `CLARK` introduces a faster strategy for the search and removal of clean component. However, it can be instable when dirty sidelobes are high. `MX` cleans the largest region of the dirty map because the source removal happens in the plane. However, it is slower than `CLARK` because of the repeated imaging step and it shares the possible `CLARK` instabilities because it uses the same search strategy.

`HOGBOM`, `CLARK` and `MX` may introduce artifacts as parallel stripes in the clean map when dealing with smooth, extended structures. `SDI`, `MRC` and `MULTI` introduce (in principle) a better handling of those extended sources. `SDI` is a rough attempt while `MRC` and `MULTI` introduce the notion of cleaning at different spatial scales.
