cds-question@unistra.frquasarsactive-galactic-nucleivisible-astronomyWide-band photometryredshiftedSpectra, position, magnitudes and colors are presented for 485 faint (B_J_<20.5) emission line objects selected with the ultraviolet-excess (UVX) criterion on a area of 24.6 sq. deg. in the South Galactic Pole. The objects were selected from the analysis of pixel-to-pixel stacking of COSMOS scans of UKST U_J_ and R plates. The candidates were observed with the Meudon-ESO Fiber Optics System (MEFOS) at the ESO 3.6m telescope. 429 type 1 AGNs have been identified (373 in the redshift range 0.3<z<=2.2). This sample has allowed the measure of a difference on the QSO clustering evolution in comparison with that found for galaxies (La Franca et al., 1998ApJ...497..529L). The region is part of the ESO Imaging Survey (EIS) and of the 2dF QSO redshift survey.1999A&AS..140..351Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/140/351CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/207 : Quasars and Active Galactic Nuclei (8th Ed.)
