Note : this is the description file of the original catalog.
This HTML page corresponds well to the original description, but some minor
changes in the format may have been introduced in the FITS output
files in order to allow for arithmetic operations on quantities
such as coordinates and times. h:m:s and d:m:s units are normally
converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the
units; the value given in the HTML files supersedes the value indicated in the ReadMe
file for this catalogue.

Description:
This catalogue is a compilation of all known AGNs presented in a
compact and convenient form. It is an update of the previous versions;
and as in the previous editions no information about absorption lines
of X-ray properties are given, but absolute magnitudes are given,
assuming Ho=71km/s/Mpc and q0=0 (notice the change of cosmology:
Ho was assumed to be 50km/s/Mpc in the previous editions). When
available, the 20cm and 6cm radio flux are given.
The present edition of this catalogue contains the quasars with
measured redshift known prior to July 1st, 2009. It contains 133336
quasars, 1374 BL Lac objects and 34231 active galaxies (including
15627 Seyfert 1's), almost doubling the number listed in the 12th
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.
Note (5): the flux is not reported if too large to fit in the column
(i.e. >=100Jy), like Cen A (NGC 5128)

History:
* 02-Feb-2010: original version, with a cosmology of Ho=50km/s/Mpc
* 31-Mar-2010: change in the cosmology: Ho=71km/s/Mpc was adopted.
* 20-Feb-2012: corrected 3 quasars and removed one duplicate:
-- the positions of SDSS J00480-1051B and SDSS J00480-1051A has
an identical position (00:48:00.9-10:51:46), fixed
-- the 2 quasars H 1400#16A and SDSS J13523+1302 are identical
at position 13:52:18.2+13:02:41; records merged.
