The Australia Telescope 20 GHz (AT20G) Survey

The AT20G Survey is a blind survey carried out at 20 GHz with the Australia Telescope Compact Array (ATCA) from 2004-2008. The final catalogue consists of 5890 sources above a flux limit of 40 mJy and is an order of magnitude larger than any previous catalogue of high frequency radio sources. A full description of the survey and resulting catalogue is presented in the source catalogue paper: Murphy, T. et al., 2009 (astro-ph listing here).

Version 1 of the AT20G catalogue is now available (2009 November 3rd): at20gcat.Oct-25-2009

Description of catalogue format

The distribution of sources, divided into 20 GHz flux bins, is shown below. The empty patches near the equator at approximately 18 hrs are due to poor weather during our observations.
