Full description

This collection contains post-processed images and catalogues from the first data release of the Variables And Slow Transients (VAST) Extragalactic survey. The post-processing procedure is described in detail in de Ruiter+2026. In short, a single astrometric shift and flux correction is applied per observation (against RACS-low2, Duchesne+in prep), to make source association more reliable and the light curves more robust. These corrections are applied to both the images and the catalogues. The data products presented here include 2945 post-processed images and catalogues, associated with the first data release of the extragalactic part of the VAST survey. The file structure and formats are similar to the default ASKAPSoft fits images and Selavy catalogues.
