cds-question@unistra.frsurveysx-ray-sourcesmilky-way-galaxyvisible-astronomysloan-photometryh-alpha-photometryAs part of the Chandra Galactic Bulge Survey (GBS), we present a catalogue of optical sources in the GBS footprint. This consists of two regions centered at Galactic latitude b=1.5{deg} above and below the Galactic Centre, spanning (lxb)=(6{deg}x1{deg}). The catalogue consists of 2 or more epochs of observations for each line of sight in r', i' and H{alpha} filters. The catalogue is complete down to r'=20.2 and i'=19.2mag; the mean 5{sigma} depth is r'=22.5 and i'=21.1mag. The mean root-mean-square residuals of the astrometric solutions is 0.04-arcsec. We cross-correlate this optical catalogue with the 1640 unique X-ray sources detected in Chandra observations of the GBS area, and nd candidate optical counterparts to 1480 X-ray sources. We use a false alarm probability analysis to estimate the contamination by interlopers, and expect ~10 0 per cent of optical counterparts to be chance alignments. To determine the most likely counterpart for each X-ray source, we compute the likelihood ratio for all optical sources within the 4{sigma} X-ray error circle. This analysis yields 1480 potential counterparts (~90 per cent of the sample). 584 counterparts have saturated photometry (r'<=17, i'<=16), indicating these objects are likely foreground sources and the real counterparts. 171 candidate counterparts are detected only in the i' -band. These sources are good qLMXB and CV candidates as they are X-ray bright and likely located in the Bulge.2016MNRAS.458.4530Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/4530CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/210/18 : X-ray survey of the Galactic Bulge (CXOGBS) (Jonker+, 2014)J/ApJS/214/10 : Optical counterparts of Chandra GBS sources (Britt+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/458/4530https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/458/4530http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/458/4530https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/458/4530https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/458/4530http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/458/4530GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/458/4530/table1 (List of the pointing centre and the seeing towards each field in the r'-band)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/4530/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/4530/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/4530/table1?GETtext/xml+votable180.050000true266.4408259-32.24642560.005555555555555556Cone search capability for table J/MNRAS/458/4530/mercat1 (merged catalogues with rgiHalpha data (among 3,144,075 stars))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/4530/mercat1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/4530/mercat1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/4530/mercat1?GETtext/xml+votable180.050000true266.769894-32.5550040.005555555555555556Cone search capability for table J/MNRAS/458/4530/mercat2 (merged catalogues with riHalpha data (among 38,387,310 stars))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/4530/mercat2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/4530/mercat2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/4530/mercat2?GETtext/xml+votable180.050000true266.284828-32.2908130.005555555555555556Cone search capability for table J/MNRAS/458/4530/conserv (Most likely optical counterparts of the most conservative determined from the likelihood ratio method (table 7 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/4530/conserv?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/4530/conserv?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/4530/conserv?GETtext/xml+votable180.050000true264.36825611-29.133936110.005555555555555556Cone search capability for table J/MNRAS/458/4530/nohalpha (Most likely optical counterparts determined with only r' and i' detections from the likelihood ratio method (table 7 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/4530/nohalpha?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/4530/nohalpha?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/4530/nohalpha?GETtext/xml+votable180.050000true264.36825611-29.133936110.005555555555555556Cone search capability for table J/MNRAS/458/4530/onlyi (Most likely optical counterparts determined with only i' detections from the likelihood ratio method (table 7 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/4530/onlyi?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/4530/onlyi?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/4530/onlyi?GETtext/xml+votable180.050000true264.36825611-29.133936110.0055555555555555565/7204 7212-7213 6/28805 28807 28814-28815 28820 28822-28823 28825 28828-28829 28836-28837 28839 28866-28867 28872-28873 28896 28898 28904https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/458/4530?format=asciiX-rayOpticaldefaultJ/MNRAS/458/4530/table1List of the pointing centre and the seeing towards each field in the r'-band_RA.icrsRight ascension (ICRS) (computed by VizieR, not part of the original data.
