Abstract:

The Automated Quasar Detection (AQD) technique has been applied to six connected fields near the South Galactic Pole. A comparison with the Véron & Véron catalogue (1993) and the Cristiani et al. compilation (1995) shows that AQD re--discovered % of the known quasars with non--overlapping objective--prism spectra present in these fields (% if only the high probability candidates are considered). A list of the 1592 high probability candidates is given, including the results of cross--correlation with X--ray and radio catalogues.

Key words: quasars: general --- surveys
