Abstract
The Australia Telescope 20 GHz (AT20G) survey is a large area (2 π sr), sensitive (40 mJy), high frequency (20 GHz) survey of the southern sky. The survey was conducted in two parts: an initial fast scanning survey, and a series of more accurate follow-up observations. The follow-up survey catalog has been presented by Murphy et al. (MNRAS 402:2403, ). In this paper we discuss the hardware setup and scanning survey strategy as well as the production of the scanning survey catalog. [ABSTRACT FROM AUTHOR]
