cds-question@unistra.frvariable-starsapparent-magnitudeWe present the most comprehensive picture ever obtained of the central parts of the Milky Way probed with RR Lyr variable stars. This is a collection of 38257 RR Lyr stars detected over 182 square degrees monitored photometrically by the Optical Gravitational Lensing Experiment (OGLE) in the most central regions of the Galactic bulge. The sample consists of 16804 variables found and published by the OGLE collaboration in 2011 and 21453 RR Lyr stars newly detected in the photometric databases of the fourth phase of the OGLE survey (OGLE-IV). 93% of the OGLE-IV variables were previously unknown. The total sample consists of 27 258 RRab, 10825 RRc, and 174 RRd stars. We provide OGLE-IV I- and V-band light curves of the variables along with their basic parameters. About 300 RR Lyr stars in our collection are plausible members of 15 globular clusters. Among others, we found the first pulsating variables that may belong to the globular cluster Terzan 1 and the first RRd star in the globular cluster M54. Our survey also covers the center and outskirts of the Sagittarius Dwarf Spheroidal Galaxy enabling studies of the spatial distribution of the old stellar population from this galaxy.2014AcA....64..177Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/64/177CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/213 : OGLE Galactic Bulge periodic variables (Udalski+ 1996)J/ApJ/651/197 : OGLE Galactic Bulge fundamental-mode RR Lyrae (Collinge+, 2006)J/AcA/61/1 : VI light curves of Galactic Bulge RR Lyrae (Soszynski+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/64/177https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/64/177http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/64/177https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/64/177https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/64/177http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/64/177GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/64/177/ident (Identification of stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/64/177/ident?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/64/177/ident?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/64/177/ident?GETtext/xml+votable180.050000true256.2812083-32.63255560.0055555555555555564/1794-1795 1798 1803 1805 5/7174-7175 7198-7201 7204-7205 7209-7211 7216-7217 7219 7224 7226-7227 7230 7242-7243 7296 7300-7301 7312-7313 7316 7318 10591 10622 11967 12008-12010 6/28682-28683 28685-28687 28744 28746-28747 28750-28751 28756-28757 28759 28784 28786-28787 28790 28808 28811 28814-28815 28825-28829 28831-28833 28835 28872-28873 28902-28903 28914 28916 28924 28926 28928 28966-28967 29056 29058-29059 29062 29064-29066 29068 29088 29188-29189 29191 29256-29257 29259-29261 29268 29270 29277 29279 42349-42351 42357 42359-42360 42362-42363 42449 42452-42453 42492 42494-42495 42837 48011 48014-48015 48044https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/64/177?format=asciidefaultJ/AcA/64/177/identIdentification of starsrecnoRecord number assigned by the VizieR team.
