cds-question@unistra.frvariable-starsphotometryWe present a catalog of 1888 fundamental-mode RR Lyrae stars detected in the Galactic bulge fields of the second phase of the Optical Gravitational Lensing Experiment (OGLE). The catalog includes basic parameters of the light curves, identifications of Blazhko frequencies, V-I colors at minimum light (for most stars), and other information for each star. We detect a high rate of incidence of the Blazhko phenomenon (at least 27.6%), including unprecedentedly many frequency triplets, which we attribute to our sensitive search method. We find that the minimum light V-I color (useful as a reddening indicator) grows slowly redder with increasing period and exhibits a star-to-star scatter of approximately 0.07mag. We use this color to evaluate the zero-point accuracy of the reddening map of the Galactic bulge derived from OGLE data and find that in addition to low-level random errors or resolution effects (responsible for much of the scatter), the map may systematically over-represent E(V-I) by approximately 0.05mag in most fields.2006ApJ...651..197Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/651/197CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/52/217 : OGLE VI photometry of Galactic Bulge (Udalski+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/651/197https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/651/197http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/651/197https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/651/197https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/651/197http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/651/197GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/651/197/table1 (RRab sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/651/197/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/651/197/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/651/197/table1?GETtext/xml+votable180.050000true270.62985-30.41990.0055555555555555565/7179 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 28910 28911 29058 29059 29062 29065 29068 42349 42351https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/651/197?format=asciiOpticaldefaultJ/ApJ/651/197/table1RRab samplerecnoRecord number assigned by the VizieR team.
