cds-question@unistra.frmagellanic-cloudsvariable-starsastronomical-object-identificationWe present a comparison of the Gaia DR1 samples of pulsating variable stars - Cepheids and RR Lyr type - with the OGLE Collection of Variable Stars aiming at the characterization of the Gaia mission performance in the stellar variability domain. Out of 575 Cepheids and 2322 RR Lyr candidates from the Gaia DR1 samples located in the OGLE footprint in the sky, 559 Cepheids and 2302 RR Lyr stars are genuine pulsators of these types. The number of misclassified stars is low indicating reliable performance of the Gaia data pipeline. The completeness of the Gaia DR1 samples of Cepheids and RR Lyr stars is at the level of 60-75% as compared to the OGLE Collection dataset. This level of completeness is moderate and may limit the applicability of the Gaia data in many projects.2016AcA....66..433Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/66/433CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/66/433https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/66/433http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/66/433https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/66/433https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/66/433http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/66/433GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/66/433/table1 (Cross-identification table of OCVS and Gaia Cepheid)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/66/433/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/66/433/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/66/433/table1?GETtext/xml+votable180.050000true72.39165917-66.975842780.005555555555555556Cone search capability for table J/AcA/66/433/table3 (Cross-identification table of OCVS and Gaia RR Lyrae)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/66/433/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/66/433/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/66/433/table3?GETtext/xml+votable180.050000true69.00026083-66.747056940.005555555555555556Cone search capability for table J/AcA/66/433/table2 (Misclassified variables from the Gaia lists located in the OGLE-IV footprint in the sky)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/66/433/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/66/433/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/66/433/table2?GETtext/xml+votable180.050000true78.887135-67.144023060.005555555555555556Cone search capability for table J/AcA/66/433/table5 (Misclassified variables from the Gaia lists located outside the OGLE-IV footprint in the sky)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/66/433/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/66/433/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/66/433/table5?GETtext/xml+votable180.050000true119.28652306-62.324500560.0055555555555555565/8277-8278 8281-8284 8293 8295 8304-8305 9385-9386 6/33087 33103 33107 33116-33118 33123 33140 33144-33146 33177 33179 33202 33204-33205 33209 33224 33232 33234 33252 33540 33792 37479 37483-37484 37502 37519 37523 37525-37526 37529 37531-37533 37539 37548 37552-37554 37556 37572 37576 37584-37586 389121.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/66/433?format=asciidefaultJ/AcA/66/433/table1Cross-identification table of OCVS and Gaia CepheidrecnoRecord number assigned by the VizieR team.
