HEASARC Archive |
The 60-month All-Sky Burst Alert Telescope Survey of Active Galactic Nuclei and the Anisotropy of Nearby AGNs Ajello M., Alexander D.M., Greiner J., Madejski G.M., Gehrels N., Burlon D. <Astrophysical Journal, 749, 21 (2012)> =2012ApJ...749...21A
Name
The Swift BAT source designation using the J2000.0 equatorial
coordinates truncated to 0.1 minutes of time in RA and 1 arcminute in Dec.
RA
The Right Ascension of the Swift BAT source in the selected equinox. This
was given in J2000 decimal degrees to a precision of 0.001 degrees (3.6
arcseconds) in the original table.
Dec
The Declination of the Swift BAT source in the selected equinox. This
was given in J2000 decimal degrees to a precision of 0.001 degrees (3.6
arcseconds) in the original table.
LII
The Galactic Longitude of the Swift BAT source.
BII
The Galactic Latitude of the Swift BAT source.
Error_Radius
The positional error of the Swift BAT source, in arcseconds.
This was converted by the HEASARC from the units of arcminutes given in the
original table.
Flux
The observed flux of the Swift BAT source in the 15 to 55 keV energy
interval, in erg/s/cm2.
SNR
The signal-to-noise ratio of the Swift BAT source. The selected sources
are all >= 5 sigma.
Alt_Name
The Swift BAT source identification obtained by the authors from
cross-correlating their catalog with the catalogs listed in Section 2
of the reference paper.
AGN_Type
The source type of AGN using the following schema (where sources
classed as AGNs lack an exact optical classification):
AGN type Meaning BLAZAR GiP Galaxy in Pair of Galaxies LINER QSO RG Radio Galaxy Sy Seyfert
Redshift
The redshift of the Swift BAT source.
Photon_Index
The power-law photon index, Gamma, of the Swift BAT source
in the 15 to 55 keV band.
Photon_Index_Error
The uncertainty in the power-law photon index, Gamma, of
the Swift BAT source.
Log_Lx
The logarithm of the k-corrected X-ray luminosity of the Swift BAT
source, in erg/s, computed according to equation (1) in the reference paper
and assuming a standard concordance cosmology with H0 = 71 km s-1
Mpc-1, OmegaM = 1 - OmegaLambda = 0.27.
Class
The HEASARC Browse object classification based on the value of the
agn_type parameter.
