Description
We present the Data Release 9 Quasar (DR9Q) catalog from the Baryon
Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey
III. The catalog includes all BOSS objects that were targeted as quasar
candidates during the survey, are spectrocopically confirmed as quasars
via visual inspection, have luminosities Mi[z = 2] < -20.5
(in a ΛCDM cosmology with H0 = 70 km s-1
Mpc-1, ΩM = 0.3, and
ΩΛ = 0.7) and either display at least one
emission line with full width at half maximum (FWHM) larger than 500 km
s-1 or, if not, have interesting/complex absorption features.
It includes as well, known quasars (mostly from SDSS-I and II) that were
reobserved by BOSS. This catalog contains 87 822 quasars (78 086 are new
discoveries) detected over 3275 deg2 with robust
identification and redshift measured by a combination of principal
component eigenspectra newly derived from a training set of 8632 spectra
from SDSS-DR7. The number of quasars with z > 2.15 (61 931) is ~2.8
times larger than the number of z > 2.15 quasars previously known.
Redshifts and FWHMs are provided for the strongest emission lines (C iv,
C iii], Mg ii). The catalog identifies 7533 broad absorption line
quasars and gives their characteristics. For each object the catalog
presents five-band (u, g, r, i, z) CCD-based photometry with typical
accuracy of 0.03 mag, and information on the morphology and selection
method. The catalog also contains X-ray, ultraviolet, near-infrared, and
radio emission properties of the quasars, when available, from other
large-area surveys. The calibrated digital spectra cover the wavelength
region 3600-10 500 Å at a spectral resolution in the range 1300
< R < 2500; the spectra can be retrieved from the SDSS Catalog
Archive Server. We also provide a supplemental list of an additional 949
quasars that have been identified, among galaxy targets of the BOSS or
among quasar targets after DR9 was frozen.
Catalog is only available at the CDS via anonymous ftp to
cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/548/A66
