High probability quasar candidates
Listed in IVOA Registry (Virtual Observatory)
The Automated Quasar Detection (AQD) technique has been applied to six connected fields near the South Galactic Pole.
Description
A comparison with the Veron & Veron catalogue (1993) <VII/188> and the Cristiani et al. compilation (1995A&AS..112..347C) shows that AQD rediscovered ~75% of the known quasars with non-overlapping objective-prism spectra present in these fields (~40% if considering only the high degree candidates). A list of 1592 high grade candidates is given, including the results of cross-correlation with X-ray and radio catalogues.
