论文摘要
快速ASKAP连续调查（RACS）是首次通过完整的36-澳大利亚平方英里阵列途径（ASKAP）望远镜进行的首次大区域调查。 RACS将提供ASKAP天空的浅模型，该模型将有助于对未来深层ASKAP调查的校准。 RACS将覆盖西澳大利亚州的Askap网站可见的整个天空，并将覆盖$ 700-1800 $ MHz的整个Askap乐队。 RACS图像通常比现有的NRAO VLA Sky Survey（NVSS）和悉尼大学Molonglo Sky Survey（SUMSS）无线电调查更深，并且具有更好的空间分辨率。所有RACS调查产品都将是公开的，包括无线电图像（具有$ \ sim 15 $ ARCSECNENTOUSTION）和大约300万个带有光谱指数和极化信息的源组件的目录。在本文中，我们介绍了RACS调查以及903张图像的第一个数据发布，涵盖了偏斜以南的天空$+41^\ Circ $以887.5 MHz为中心的288 MHz频段进行。
The Rapid ASKAP Continuum Survey (RACS) is the first large-area survey to be conducted with the full 36-antenna Australian Square Kilometre Array Pathfinder (ASKAP) telescope. RACS will provide a shallow model of the ASKAP sky that will aid the calibration of future deep ASKAP surveys. RACS will cover the whole sky visible from the ASKAP site in Western Australia, and will cover the full ASKAP band of $700-1800$ MHz. The RACS images are generally deeper than the existing NRAO VLA Sky Survey (NVSS) and Sydney University Molonglo Sky Survey (SUMSS) radio surveys and have better spatial resolution. All RACS survey products will be public, including radio images (with $\sim 15$ arcsecond resolution) and catalogues of about three million source components with spectral index and polarisation information. In this paper, we present a description of the RACS survey and the first data release of 903 images covering the sky south of declination $+41^\circ$ made over a 288 MHz band centred at 887.5 MHz.
