VII/224             Quasars and Active Galactic Nuclei (10th Ed.)  (Veron+ 2001)

Quasars and Active Galactic Nuclei (10th Ed.) Veron-Cetty M.P., Veron P. <Astron. Astrophys. 374, 92 (2001)> =2001A&A...374...92V
ADC_Keywords: QSOs ; Active gal. nuclei ; BL Lac objects ; Description: This catalogue is an update of the previous versions. The recent publication of the first release of the 2dF quasar survey (Croom et al., 2001MNRAS.322L..29C, see Cat. VII/223) containing nearly 10,000 new QSOs, almost doubled the number of known such objects: there are now 23760 (+10546) quasars (defined as brighter than absolute B magnitude -23), 5751 (+1323) AGNs (defined as fainter than absolute B magnitude -23) of which 2765 are Seyfert 1, and 608 (+146) BL Lac objects from 2173 (+119) references. Like the ninth edition, it includes position and redshift as well as photometry (U, B, V) and 6 and 11 cm flux densities when available. The present edition this catalogue contains the quasars with measured redshift known prior to May 1st, 2001.

Note (1): this flag is blank if the object has been detected as a radio source, and is '*' if not. Note (2): this flag related to the position takes the values: 'O' for an Optical position with an accuracy better than 1arcsec 'R' for a Radio position with an accuracy better than 1arcsec 'A' for an approximative position Note (3): the classification of the object is S1 : Seyfert 1 spectrum S1h: broad polarized Balmer lines detected S1i: broad Paschen lines observed in the infrared S1n: narrow-line Seyfert 1 S1.0, S1.2, S1.5, S1.8, S1.9: intermediate Seyfert galaxies S2 : Seyfert 2 spectrum S3 : Seyfert 3 or liner S3b: Seyfert 3 or liner with broad Balmer lines S3h: Seyfert 3 or liner with broad polarized Balmer lines detected S : unclassified Seyfert S? : possibly a Seyfert H2 : nuclear HII region HP : high optical polarization (>3%) BL : confirmed BL Lac object Note (4): n_z may indicate a lower limit on z, or '*', if the redshift is measured by slitless spectroscopy.
