ASKAP Project AS110 - The Rapid ASKAP Continuum Survey (RACS): The RACS-high 1655.5 MHz images and catalogue

Data products associated with the release of the Stokes I catalogue from the Rapid ASKAP Continuum Survey (RACS) at 1655.5 MHz (RACS-high, Duchesne+2025). This work took the images of the tiles associated with the RACS-high survey at 1655.5 MHz, convolved them to a common resolution, and mosaicked them with neighbouring images to obtain near-uniform sensitivity images covering the sky up to declination +49 degrees. Released are the 1493 Stokes I images constructed in this manner, and the resulting source and component catalogue covering the region. Catalogues were made by running PyBDSF (see Mohan and Rafferty: 2015ascl.soft02007M) over each mosaicked tile image. These tile catalogues were combined together and duplicates removed.

本数据集关联1655.5 MHz频段ASKAP快速连续谱巡天（Rapid ASKAP Continuum Survey，缩写RACS）所发布的斯托克斯I（Stokes I）目录（RACS-high，杜谢内等，2025）。本次研究选取该1655.5 MHz频段RACS-high巡天的天区块图像，将其卷积至统一分辨率，并与相邻图像拼接，以生成覆盖赤纬+49°以内天区的近均匀灵敏度图像。本次发布包含以此方式生成的1493幅斯托克斯I图像，以及覆盖该天区的天体源与成分目录。目录通过在每幅拼接后的天区块图像上运行PyBDSF工具（详见Mohan与Rafferty：2015ascl.soft02007M）生成。随后将这些天区块目录进行合并，并移除重复条目。
