This page provides access to light curves and other photometric data
for objects detected by the LINEAR survey. The database was released on January 9, 2012.

The content of this database is the result of the photometric recalibration of data obtained by the asteroid survey LINEAR.
Although LINEAR was designed for astrometric discovery of moving objects, the data set described here contains over 5 billion
photometric measurements for about 25 million objects, mostly stars. We use Sloan Digital Sky Survey (SDSS) data from the
overlapping ~10,000 deg2 of sky to recalibrate LINEAR photometry and achieve errors of 0.03 mag for sources not limited by
photon statistics with errors of 0.2 mag at r ~ 18. With its 200 observations per object on average, LINEAR data provide
time domain information for the brightest four magnitudes of the SDSS survey. At the same time, LINEAR extends the deepest
similar wide-area variability survey, the Northern Sky Variability Survey, by 3 mag. We briefly discuss the properties
of about 7000 visually confirmed periodic variables, dominated by roughly equal fractions of RR Lyrae stars and eclipsing
binary stars, and analyze their distribution in optical and infrared color-color diagrams.
