Light and Motion in SDSS Stripe 82

A Description of the Catalogues

The Light-Motion-Curve Catalogue (LMCC) covers Stripe 82 from RA = 20.7h to 3.3h and from Dec. = -1.26 deg to 1.26 deg, which equates to ~249 square degrees. This Stripe has been repeatedly monitored in the u, g, r, i and z bands over a seven-year baseline. The resulting catalogue contains almost 4 million light-motion curves of stellar objects and galaxies. Along with the LMCC, we supply a number of IDL plotting tools to aid in the visualisation of the light-motion-curves. Please see the download page for more details.

We also provide what we refer to as the Higher-Level Catalogue (HLC) in 8 separate gzipped binary fits files. This catalogue supplies 235 derived quantities for each light-motion-curve, aimed at describing mean magnitudes, photometric variability and astrometric motion.

A detailed description of both the LMCC and HLC is available in the paper of Bramich et al. (2008).
