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.
