标题： The Australia Telescope 20GHz Survey: Hardware, Observing Strategy, and Scanning Survey Catalog

摘要： 澳大利亚射电望远镜20GHz(AT20G)巡天是一项大区域(2{\pi } sr)、灵敏度高(40mJy)、高频(20GHz)的南天巡天。 该巡天分为两部分：初步的快速扫描巡天，以及一系列更精确的后续观测。 后续巡天目录已由Murphy等人于2010年提出。 在本文中，我们讨论硬件设置和扫描巡天策略以及扫描巡天目录的生成。 显示英文摘要

摘要： The Australia Telescope 20GHz (AT20G) survey is a large area (2{\pi} sr), sensitive (40mJy), high frequency (20GHz) 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. 2010. In this paper we discuss the hardware setup and scanning survey strategy as well as the production of the scanning survey catalog.
