Is CLEAN Still the State-of-the-Art in Deconvolution Algorithms in Astronomical Imaging?

-- | February 23, 2017

Question: What is the state of the art of the deconvolution algorithm in astronomy imaging? As we known, clean was proposed in 1974. So does people still utilize clean now? — Shui

Answer: The CLEAN algorithm is still widely used as the standard. Other methods, such as Bayesian- or wavelet-based deconvolution, also find application for certain deconvolution problems in astronomy. There is a nice review of deconvolution algorithms by Starck, Pantin, and Murtagh which describes many of these methods.

The National Radio Astronomy Observatory is a facility of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
	Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
	The U.S. National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."
	AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
