After aggregating and re-calibrating catalog-level data from the survey, we ran a period-finding algorithm (Supersmoother) on all point-source light curves. We used color selection to identify systems that are likely to contain low-mass stars, in particular M dwarfs and white dwarfs. In total, we found 207 candidates, the vast majority of which appear to be in eclipsing binary systems. The catalog described in this paper includes 42 candidate M dwarf/white dwarf pairs, four white dwarf pairs, 59 systems whose colors indicate they are composed of two M dwarfs and whose light-curve shapes suggest they are in detached eclipsing binaries, and 28 M dwarf systems whose light-curve shapes suggest they are in contact binaries. We find no detached systems with periods longer than 3 days, thus the majority of our sources are likely to have experienced orbital spin-up and enhanced magnetic activity.2011ApJ...731...17Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/731/17CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/A+A/510/A100 : Four new SDSS eclipsing systems (Southworth+, 2010)J/ApJS/186/233 : Variable point sources in SDSS stripe 82.
