cds-question@unistra.frmagellanic-cloudseclipsing-binary-starsphotometryWe present new version of the OGLE-II catalog of eclipsing binary stars detected in the Small Magellanic Cloud, based on Difference Image Analysis catalog of variable stars in the Magellanic Clouds containing data collected from 1997 to 2000. We found 1351 eclipsing binary stars in the central 2.4 square degree area of the SMC. 455 stars are newly discovered objects, not found in the previous release of the catalog. The eclipsing objects were selected with the automatic search algorithm based on the artificial neural network. The full catalog with individual photometry is accessible from the OGLE INTERNET archive, at ftp://sirius.astrouw.edu.pl/ogle/ogle2/var_stars/smc/ecl . Regular observations of the SMC fields started on June 26, 1997 and covered about 2.4 square degrees of central parts of the SMC. Reductions of the photometric data collected up to the end of May 2000 were performed with the Difference Image Analysis (DIA) package.2004AcA....54....1Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/54/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/48/147 : OGLE SMC BVI photometry (Udalski+ 1998)ftp://sirius.astrouw.edu.pl/ogle/ogle2/var_stars/smc/ecl : OGLE Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/54/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/54/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/54/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/54/1https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/54/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/54/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/54/1/table2 (Eclipsing binaries in the SMC)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/54/1/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/54/1/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/54/1/table2?GETtext/xml+votable180.050000true9.0728333-73.22552780.0055555555555555566/33294-33295 33304 33306 33316-33317 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/54/1?format=asciiOpticaldefaultJ/AcA/54/1/table2Eclipsing binaries in the SMCPerPerioddtime.perioddoubleEpochT0-2450000dtime.epochdoublerecnoRecord number assigned by the VizieR team.
