VST-ATLAS completeness in the NGC based on spectroscopically confirmed QSOs from 2QZ, 2QDES, and eBOSS. Confirmed QSOs-stellar and Confirmed QSOs-exten. refer to the number of confirmed QSOs that are picked up as stars and galaxies, respectively, in the VST-ATLAS catalogue prior to making any QSO selection.
