cds-question@unistra.frmagellanic-cloudsvariable-starsphotometrysurveysWe present a comprehensive analysis of the Gaia South Ecliptic Pole (GSEP) field, 5.3 square degrees area around the South Ecliptic Pole on the outskirts of the LMC, based on the data collected during the fourth phase of the Optical Gravitational Lensing Experiment, OGLE-IV. The GSEP field will be observed during the commissioning phase of the ESA Gaia space mission for testing and calibrating the Gaia instruments. We provide the photometric maps of the GSEP region containing the mean VI photometry of all detected stellar objects and their equatorial coordinates. We show the quality and completeness of the OGLE-IV photometry and color-magnitude diagrams of this region. We conducted an extensive search for variable stars in the GSEP field leading to the discovery of 6789 variable stars. In this sample we found 132 classical Cepheids, 686 RR Lyr type stars, 2819 long-period, and 1377 eclipsing variables. Several objects deserving special attention were also selected, including a new classical Cepheid in a binary eclipsing system.2012AcA....62..219Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/62/219CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toftp://ftp.astrouw.edu.pl/ogle/ogle4/GSEP : OGLE-GSEP Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/62/219https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/62/219http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/62/219https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/62/219https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/62/219http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/62/219GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/62/219/list_hpm (List of stars with the highest proper motions ({mu}>100mas/yr) or parallaxes ({pi}>10mas))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/62/219/list_hpm?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/62/219/list_hpm?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/62/219/list_hpm?GETtext/xml+votable180.050000true87.6962083-66.00727780.005555555555555556Cone search capability for table J/AcA/62/219/list_pm (List of stars with proper motions >20mas/yr)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/62/219/list_pm?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/62/219/list_pm?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/62/219/list_pm?GETtext/xml+votable180.050000true86.7594583-66.05352780.005555555555555556Cone search capability for table J/AcA/62/219/list_gal (List of galaxies with their parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/62/219/list_gal?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/62/219/list_gal?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/62/219/list_gal?GETtext/xml+votable180.050000true90.105375-68.06483330.005555555555555556Cone search capability for table J/AcA/62/219/list_sn (List of transients with their parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/62/219/list_sn?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/62/219/list_sn?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/62/219/list_sn?GETtext/xml+votable180.050000true91.0605833-66.006750.005555555555555556Cone search capability for table J/AcA/62/219/list_var (List of variable stars with their parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/62/219/list_var?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/62/219/list_var?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/62/219/list_var?GETtext/xml+votable180.050000true86.731375-66.51322220.005555555555555556Cone search capability for table J/AcA/62/219/stars (All stars in the South Ecliptic Pole)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/62/219/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/62/219/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/62/219/stars?GETtext/xml+votable180.050000true89.969625-68.07619440.0055555555555555565/8277 9386 6/33104-33105 33107 33792-33794 37538-37539 38912 38914https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/62/219?format=asciiOpticaldefaultJ/AcA/62/219/list_mapList of OGLE-IV maps of the Gaia South Ecliptic Pole fieldsrecnoRecord number assigned by the VizieR team.
