ASKAP Project AS110 - The Rapid ASKAP Continuum Survey: cataloguing the sky at 1367.5 MHz and the second data release of RACS-mid

Data products associated with the release of the Stokes I catalogue (Duchesne+2023b) from the Rapid ASKAP Continuum Survey (RACS) at 1367.5 MHz (RACS-mid). This work took the images of the tiles associated with RACS-mid survey (see Duchesne+2023a) at 1367.5 MHz (144 MHz bandwidth), 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 mosaiced tile image. These tile catalogues were combined together and duplicates removed. An additional set of images are produced at a fixed resolution of 25" times 25", to match the RACS catalogue at 887.5 MHz (RACS-low, Hale+2021) with coverage up to declination +30 degrees. An auxiliary catalogue is produced with these 25" images intended for simple cross-matching to the RACS-low catalogue or for users who required a position-independent resolution. See Duchesne+2023b for details on the individual catalogues.
