cds-question@unistra.frsurveysmagellanic-cloudsvariable-starsphotometryWe present the first edition of a catalog of variable stars found in the Magellanic Clouds using OGLE-II data obtained during four years: 1997-2000. The catalog covers about 7 square degrees of the sky - 21 fields in the Large Magellanic Cloud and 11 fields in the Small Magellanic Cloud. All variables were found with the Difference Image Analysis (DIA) software. The catalog is divided into two sections. The DC section contains FITS reference images (obtained by co-adding 20 best frames for each field) and profile photometry (DOPHOT) of all variable stars on those images. The AC section contains flux variations and magnitudes of detected variable stars obtained with DIA as well as with DOPHOT. The errors of magnitude measurements are 0.005mag for the brightest stars (I<16mag) then grow to 0.08mag at 19mag stars and to 0.3mag at 20.5mag. Typically, there are about 400 I-band data points and about 30 V and B-band data points for more than 68 000 variables. The stars with high proper motions were excluded from this catalog and will be presented in a separate paper. A detailed analysis and classification of variable stars will be presented elsewhere. The catalog is available in electronic form via FTP and through WWW interface from the OGLE Internet archive. The FTP catalog contains approximately 2 GB of data.2001AcA....51..317Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/51/317CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/49/223 : BVI photometry of OGLE LMC Cepheids (Udalski+, 1999)J/AcA/49/543 : OGLE LMC + SMC Cepheids VI photometry (Pietrzynski+, 1999)J/AcA/48/147 : OGLE SMC BVI photometry (Udalski+ 1998)J/AcA/50/307 : OGLE LMC BVI photometry (Udalski+, 2000)J/AcA/49/521 : OGLE LMC star clusters BVI photometry (Pietrzynski+, 1999)J/AcA/50/337 : OGLE LMC star clusters (Pietrzynski+, 2000)J/AcA/48/175 : OGLE SMC clusters (Pietrzynski+ 1998)J/AcA/50/355 : OGLE Multiple Cluster Candidates in LMC (Pietrzynski+, 2000)J/AcA/48/563 : BVI photometry of OGLE SMC eclipsing binaries (Udalski+, 1998)J/AcA/53/1 : OGLE eclipsing binaries in LMC (Wyrzykowski+, 2003)J/AcA/54/1 : OGLE II SMC eclipsing binaries (Wyrzykowski+, 2004)J/AcA/49/437 : BVI photometry of OGLE SMC Cepheids (Udalski+, 1999)J/AcA/53/93 : OGLE RR Lyrae in LMC (Soszynski+, 2003)http://sirius.astrouw.edu.pl/~ogle/ogle2/dia/ : OGLE DIA Home Pageftp://sirius.astrouw.edu.pl/ogle : OGLE Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/51/317https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/51/317http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/51/317https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/51/317https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/51/317http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/51/317GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/51/317/table1 (LMC and SMC fields observed by OGLE-II)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/51/317/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/51/317/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/51/317/table1?GETtext/xml+votable180.050000true83.45417-70.102780.005555555555555556Cone search capability for table J/AcA/51/317/ogle2mc (OGLE-II variables in the Magellanic Clouds)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/51/317/ogle2mc?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/51/317/ogle2mc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/51/317/ogle2mc?GETtext/xml+votable180.050000true83.17116-70.56741310.0055555555555555565/8272 8274 6/3791 3802-3803 3813 3815 3824 3826 33052-33053 33055 33076-33077 33120-33121 33295 33306 33316-33317https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/51/317?format=asciidefaultJ/AcA/51/317/table1LMC and SMC fields observed by OGLE-IIrecnoRecord number assigned by the VizieR team.
