cds-question@unistra.frglobular-star-clusterspulsarsx-ray-sourcesThe Chandra/ACIS-I detectors observed NGC 5139 in imaging mode for two continuous periods (2000 January 24 02:15-09:46 and January 25 04:33-17:24 TT) for a total exposure of ~68.6ks. We combined the two observations and analyzed them as one. We searched for point sources using CELLDETECT, using only the 0.1-2.5keV energy range, excluding regions less than 16 pixels from the detector edges and keeping only sources with signal-to-noise ratio (S/N)>5.0. We find 40 X-ray point sources over the four ACIS-I chips and chip S2 of ACIS-S, which are numbered in order of decreasing S/N in Table 1.2002ApJ...578..405Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/578/405CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/578/405https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/578/405http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/578/405https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/578/405https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/578/405http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/578/405GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/578/405/table1 (Chandra X-Ray Sources in the Field of NGC 5139)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/578/405/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/578/405/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/578/405/table1?GETtext/xml+votable180.050000true201.46754583-47.318902780.0055555555555555566/43225 43227https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/578/405?format=asciiX-rayRadiodefaultJ/ApJ/578/405/table1Chandra X-Ray Sources in the Field of NGC 5139dof?
