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)
    Note (6): in qso.dat, this source was erroneously identified to PKS 2031+21.
         The change of "PKS 2031+21" into "GB6 B2107+3520" was made by CDS.

    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.
      * 30-Jan-2023: in qso.dat, this source was erroneously identified to
            PKS 2031+21. "PKS 2031+21" changed into "GB6 B2107+3520"
