The AT 20 GHz Survey
by Ron Ekers (CASS)
The AT20G Survey is a blind 20 GHz survey of the entire southern sky with Galactic latitude |b| > 1.5 degrees. Observations were carried out using the Australia Telescope Compact Array (ATCA) from 2004 to 2008. The final AT20G catalogue consists of 5890 sources above a 20 GHz flux density limit of 40 mJy and includes near-simultatneous observations at 4.8 and 8.6 GHz for most sources south of -15 degrees.

A full description of the survey and resulting catalogue is presented in the source catalogue paper by Murphy et al. 2010. A detailed analysis of the AT20G sample is presented in Massardi et al. 2011.
