cds-question@unistra.frgalaxy-planesmilky-way-galaxyvariable-starseclipsing-binary-starsWe have conducted a deep photometric survey of a 0.5deg*0.5deg area of the Galactic Plane using the WFI instrument on the 2.2-m ESO telescope on La Silla, Chile. The dataset comprises a total of 267 R-band images, 204 from a 16 day observation run in 2005, supplemented by 63 images from a six week period in 2002. Our reduction employed the new numerical kernel difference image analysis method as implemented in the pySIS3 code and resulted in more than 500000 lightcurves of stars down to a magnitude limit of R~24.5. A search for variable stars resulted in the detection of 1318 variables of different types. 1011 of these are eclipsing or contact binary stars. A number of the contact binaries have low mass-ratios and several of the detached binaries appear to have low-mass components. Three candidate contact binaries have periods at the known cut off including two with periods lower than any previously published. Also identified are 3 possible pre-main sequence detached eclipsing binaries.2010A&A...519A..12Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/519/A12CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/519/A12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/519/A12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/519/A12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/519/A12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/519/A12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/519/A12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/519/A12/table2 (Catalogue of variable stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/519/A12/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/519/A12/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/519/A12/table2?GETtext/xml+votable180.050000true245.1571667-53.42402780.0055555555555555566/42150-42151 421572.762881831355591e-19 3.3785437584409506e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/519/A12?format=asciiOpticaldefaultJ/A+A/519/A12/table2Catalogue of variable starsrecnoRecord number assigned by the VizieR team.
