Description
This paper reports an update to the QUEST1 (QUasar Equatorial Survey
Team, Phase 1) Variability Survey (QVS) light curve catalog, which links
QVS instrumental magnitude light 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 16,728 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 214,941 QUEST1
objects.
Based on observations obtained at the Llano del Hato National
Astronomical Observatory, operated by the Centro de Investigaciones de
Astronomía for the Ministerio de Ciencia y Tecnologia of
Venezuela.
