Abstract:
This paper reports an update to the QUEST1 (QUasar Equatorial Survey
Team, Phase 1) Variability Survey (QVS) light curve catalog, which
links QVS instrumental Light curve magnitude at jdlight curves to
Sloan Digital Sky Survey (SDSS) objects and photometry. In the time
since the original QVS catalog release, the overlap between publicly
available SDSS data and QVS data has increased by 8% in sky coverage
and 16728 in number of matched objects. The astrometric matching and
the treatment of SDSS masks have been refined for the updated catalog.
We report on these improvements and present multiple bandpass light
curves, global variability information, and matched SDSS photometry
for 214941 QUEST1 objects.
Description:
QUEST1 constructed a 16-chip CCD camera to be used on the 1m Schmidt
telescope at the Llano del Hato National Astronomical Observatory in
Venezuela. Normally operated in the drift-scan mode, an equatorial
scan will expose any point on the sky for 143s and result in limiting
magnitudes of B=18.5, V=19.2, and R=19.5 at S/N=10. These data were
collected between 1999 February and 2001 April.
