VizieR Online Data Catalog: KiDS DR3 QSO catalog (Nakoneczny+, 2019)

The released catalog includes all the KiDS DR3 objects which were subject to the classification (the inference set). Apart from basic columns taken from KiDS DR3 (IDs and coordinates), we add the resulting probabilities for each class in QSO, STAR and GALAXY columns. The final classification, given by the class with the highest probability, is provided in the CLASS column. To obtain the full catalog of all the 190k quasars candidates, one has to query CLASS == "QSO", while the high purity catalog is accessible by taking QSO>0.8 (see the paper for more details on quality cuts).
