High dynamic range mapping of strong radio sources, with application to 3C84

Abstract

A new reduction procedure is described to correct data obtained by the Westerbork Synthesis Radio Telescope. The technique allows very high dynamic range mapping of strong radio sources by also using redundant interferometers. The performance is illustrated with 6-cm and 21-cm continuum maps of 3C84, which have a dynamic range of about 10,000:1.
