The Large Sky Area Multi-Object Fiber Spectroscopic Telescope Quasar
  Survey: Quasar Properties from First Data Release
  We present preliminary results of the quasar survey in Large Sky Area Multi-
Object Fiber Spectroscopic Telescope (LAMOST) first data release (DR1), which
includes pilot survey and the first year regular survey. There are 3921 quasars
identified with reliability, among which 1180 are new quasars discovered in the
survey. These quasars are at low to median redshifts, with highest z of 4.83.
We compile emission line measurements around the H{\alpha}, H{\beta}, Mg II,
and C IV regions for the new quasars. The continuum luminosities are inferred
from SDSS photo- metric data with model fitting as the spectra in DR1 are
non-flux-calibrated. We also compile the virial black hole mass estimates, and
flags indicating the selec- tion methods, broad absorption line quasars. The
catalog and spectra for these quasars are available online. 28% of the 3921
quasars are selected with optical- infrared colours independently, indicating
that the method is quite promising in completeness of quasar survey. LAMOST DR1
and the on-going quasar survey will provide valuable data in the studies of
quasars.
