VERONCAT - Veron Catalog of Quasars & AGN, 12th Edition |
HEASARC Archive |
The 12th includes positions and redshifts, as well as photometry (U, B, and V) and 6-cm and 20-cm flux densities, when available. 141 objects once proposed but now rejected as quasars are NOT included in the online version of this catalog: their names and positions are listed in the Rejected_Quasars section of this help file. This HEASARC table also does NOT contain the additional information on gravitationally lensed quasars and quasar pairs listed in Tables 2 and 3 of the published paper: these tables are available in electronic form at ftp://cdsarc.u-strasbg.fr/pub/cats/VII/248/
The present edition of this catalog contains quasars with measured redshift known prior to January 1st, 2006.

Name
The most common name of the object.
RA
The Right Ascension of the object (given to a precision of 0.1 seconds
of time in the original table).
Dec
The Declination of the object (given to a precision of 1 arcsecond
in the original table).
LII
The Galactic Longitude of the object.
BII
The Galactic Latitude of the object.
Position_Flag
This flag is related to the accuracy and source for the
quoted position:
O = optical position with an accuracy better than 1 arcsecond
R = radio position with an accuracy better than 1 arcsecond
A = approximate position
Radio_Detect
This flag is 'Y' if the object has been detected in the radio
and 'N' if it has not been detected in the radio.
Flux_6_cm
The flux density at 6 cm (5 GHz) in milliJanskies (mJy).
Ref_Flux_6_cm
Numerical code of the reference for the 6-cm flux density.
A complete list of the references that are given as numerical codes
in this database can be obtained via anonymous FTP or the Web at
ftp://cdsarc.u-strasbg.fr/pub/cats/VII/248/refs.dat.gz
Flux_20_cm
The flux density at 20 cm (1.4 GHz) in milliJanskies (mJy).
Ref_Flux_20_cm
Numerical code of the reference for the 20-cm flux density.
A complete list of the references that are given as numerical codes
in this database can be obtained via anonymous FTP or the Web at
ftp://cdsarc.u-strasbg.fr/pub/cats/VII/248/refs.dat.gz
Redshift_Flag
This flag is set to 'E' if the redshift was estimated by
slitless spectroscopy, and is set to '>' if the quoted redshift is a
lower limit.
Redshift
The redshift of the object.
Object_Type
A code created by the catalog authors describing the
classification of the object:
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
Q2: type-2 quasar
Default object_type values are set to the following for objects in tables qso.dat, bllac.dat and agn.dat, if none were explicitly given in the original tables:
Table qso.dat = Q : quasar
Table bllac.dat2 = B?: presumed BL Lac object
Table agn.dat = AG: unspecified type of active galaxy
App_Mag_Flag
This flag is 'V' for a visual magnitude; 'P' for a photographic magnitude;
'B' for a blue magnitude; 'R' for a red magnitude, 'I', 'J', or 'K' for
infrared-band magnitudes; or 'O' for a magnitude from a photographic O- or J-
plate.
App_Mag
The apparent magnitude of the object, where the type of magnitude
is specified by the value of the app_mag_flag parameter.
BV_Color
The (B-V) color of the object, when known.
UB_Color
The (U-B) color of the object, when known.
Abs_Mag
The absolute magnitude of the object (a Hubble constant of
50 km/s/Mpc and a deceleration parameter of 0 have been assumed).
Ref_Chart
Numerical code of the reference for the finding chart.

Ref_App_Mag
Numerical code of the reference for the photometry.
A complete list of the references that are given as numerical codes
in this database can be obtained via anonymous FTP or the Web at

in this database can be obtained via anonymous ftp or the Web at
ftp://cdsarc.u-strasbg.fr/pub/cats/VII/248/refs.dat.gz
Broad_Type
The broad Veron object classification, a parameter
created by the HEASARC which is based on the table in which it was
listed in the original reference: objects in the qso.dat table
have been assigned a value of 'QSO', those in bllac.dat, 'BLLAC',
and those in agn.dat, 'AGN'.
Class
The HEASARC Browse classification type. The classification
value is based on the value of the Object_Type parameter.
