Description:
This catalogue is an update of the previous versions; as in the
previous editions no information about absorption lines of X-ray
properties are given, but absolute magnitudes are given, assuming
Ho=50km/s/Mpc and q_0_=0. In this edition the 20cm radio flux is
listed when available, in place of the 11cm flux.
The present edition of this catalogue contains the quasars with
measured redshift known prior to January 1st, 2006. It contains
85221 quasars, 1122 BL Lac objects and 21737 active galaxies
(including 9628 Seyfert 1s), almost doubling the number listed
in the 11th edition. Lists of known lensed quasars (table2.dat)
and double quasars (table3.dat) are also given here.

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
Q2 : type-2 quasar
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
S2?: probable Seyfert 2
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
BL?: probable BL Lac object
? : questionable BL Lac object
Note (4): n_z may indicate a lower limit on z, or
'*', if the redshift is measured by slitless spectroscopy.
