cds-question@unistra.freclipsing-binary-starssurveysWe have developed a fully automated pipeline for systematically identifying and analyzing eclipsing binaries within large data sets of light curves. The pipeline is made up of multiple tiers that subject the light curves to increasing levels of scrutiny. After each tier, light curves that did not conform to a given criteria were filtered out of the pipeline, reducing the load on the following, more computationally intensive tiers. As a central component of the pipeline, we created the fully automated Detached Eclipsing Binary Light curve fitter (DEBiL), which rapidly fits large numbers of light curves to a simple model. Using the results of DEBiL, light curves of interest can be flagged for follow-up analysis. As a test case, we analyzed the 218,699 light curves within the bulge fields of the OGLE II survey and produced 10,862 model fits. We point out a small number of extreme examples, as well as unexpected structure found in several of the population distributions. We expect this approach to become increasingly important as light-curve data sets continue growing in both size and number.2005ApJ...628..411Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/628/411CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toftp://sirius.astrouw.edu.pl/ogle/ogle2/ : OGLE II Home Pagehttp://ogledb.astrouw.edu.pl/~ogle/photdb/index.html : OGLE Photometrichttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/628/411https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/628/411http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/628/411https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/628/411https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/628/411http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/628/411GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/628/411/table4 (Parameters from the DEBiL dataset of eclipsing binary systems in the galactic bulge)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/628/411/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/628/411/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/628/411/table4?GETtext/xml+votable180.050000true270.6524167-30.43011110.0055555555555555565/7179 7182 7205 7216 7217 7220 6/28704 28706 28707 28713 28725 28727 28734 28735 28768 28770 28776 28778 28779 28782 28819 28828 28857 28860 28886 28887 28893 28908 28910 28911 29058 29059 29062 29065 29068 42349 42351https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/628/411?format=asciiOpticaldefaultJ/ApJ/628/411/table4Parameters from the DEBiL dataset of eclipsing binary systems in the galactic bulgePerPerioddtime.perioddoubleImag1I-band magnitude of large starmagphot.mag;em.opt.IdoublerecnoRecord number assigned by the VizieR team.
