cds-question@unistra.frx-ray-sourcesphotometryWe present a sample of 209 variable objects - very likely optical counterparts to the X-ray sources detected in the direction of the Galactic center by the Galactic Bulge Survey (GBS) carried out with the Chandra satellite. The variable sources were found in the databases of the OGLE long term survey monitoring regularly the Galactic bulge since 1992. The counterpart candidates were searched based on the X-ray source position in the radius of 3.9 arcsec.2012AcA....62..133Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/62/133CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/213 : OGLE Galactic Bulge periodic variables (Udalski+ 1996)J/A+A/439/559 : OGLE eclipsing binaries (bulge+lmc+smc) (Groenewegen+, 2005)J/A+A/478/659 : OGLE Be stars in Galactic Bulge (Sabogal+, 2008)J/AcA/50/1 : OGLE microlensing events in Galactic Bulge (Udalski+, 2000)J/AcA/52/217 : OGLE II.
