Crowded Field Source

资源简介：
Sources based on Service Interface Function (SIF) images of very dense regions in the sky. These sources build an add-on catalogue to the nominal Gaia catalogue. Nominal and SIF detections were not mixed to create these sources. These Sources are thus obtained from SIF image detections only. Sources already present in the nominal catalogue were removed from the SIF add-on catalogue.
