cds-question@unistra.frsurveysvariable-starsphotometryWe present the first edition of a catalog of variable stars from OGLE-II Galactic bulge data covering 3 years: 1997-1999. Typically 200-300 I band data points are available in 49 fields between -11 and +11 degrees in galactic longitude, totaling roughly 11 square degrees in sky coverage. Photometry was obtained using the Difference Image Analysis (DIA) software and tied to the OGLE data base with the DoPhot package. The present version of the catalog comprises 221801 light curves. In this preliminary work the level of contamination by spurious detections is still about 10%. Parts of the catalog have only crude calibration, insufficient for distance determinations. The next, fully calibrated, edition will include the data collected in year 2000. The data is accessible via ftp, at ftp://bulge.princeton.edu/ogle/ogle2/bulge_dia_variables2002AcA....52..129Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/52/129CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/50/421 : OGLE-II DIA BUL_SC1 field (Wozniak, 2000)J/AcA/51/175 : OGLE-II DIA microlensing events (Wozniak+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/52/129https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/52/129http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/52/129https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/52/129https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/52/129http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/52/129GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/52/129/catalog (Catalog of the Candidate Variables in OGLE-II)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/52/129/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/52/129/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/52/129/catalog?GETtext/xml+votable180.050000true270.504525-30.424290.0055555555555555565/7179 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 29064-29065 29068 42349 42351 42362https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/52/129?format=asciiOpticaldefaultJ/AcA/52/129/catalogCatalog of the Candidate Variables in OGLE-IIrecnoRecord number assigned by the VizieR team.
