ASKAP Data Products for Project AS110 (The Rapid ASKAP Continuum Survey): images and visibilities

This observatory led project will cover the whole southern sky to +40 deg Declination with ASKAP. The survey parameters will be such that observations for the entire region should take of order one week, with a target RMS of roughly ~0.25 mJy/beam. Multiple passes will be done to cover ASKAP’s full frequency range and additional epochs of the survey are planned to search for transient sources. This survey will provide a unique opportunity to study the radio sky and radio populations, in particular AGN and their role in galaxy evolution. RACS will produce a global sky model for ASKAP, and test operations from data collection and reduction to release.

该由天文台主导的项目将利用ASKAP望远镜覆盖整个南天至赤纬+40度区域。巡天参数设定为：对整个区域的观测约需一周时间，目标均方根噪声（RMS）约为0.25毫焦耳每波束（mJy/beam）。将通过多次扫描覆盖ASKAP的全部频率范围，并计划开展额外的观测期以搜寻暂现源。该巡天将为研究射电天空及射电天体群体提供独特机遇，尤其有助于探究活动星系核（AGN）及其在星系演化中的作用。RACS将为ASKAP构建全球天空模型，并测试从数据采集、处理到发布的全流程操作。
