cds-question@unistra.frx-ray-sourcesWe present a catalogue of 107 point-like X-ray sources derived from a systematic analysis of all the ROSAT PSPC observations of the galactic center region performed in 1992-1993. Besides SgrA*, the massive black hole at the galactic center, 41 X-ray sources have been positionally associated with already classified objects. Twenty are identified with foreground stars and five with known Low Mass X-ray Binaries. The majority of the sources in our catalogue still remains unidentified. They are hard and/or severely absorbed and probably represent a large population of X-ray binaries located in the galactic center region, accreting at low accretion rates, and still largely unknown.2001A&A...368..835Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/368/835CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/30 : Second ROSAT PSPC Catalog (ROSAT, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/368/835https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/368/835http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/368/835https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/368/835https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/368/835http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/368/835GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/368/835/table3 (The ROSAT PSPC Catalogue in the Galactic Center)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/368/835/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/368/835/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/368/835/table3?GETtext/xml+votable180.050000true264.60958-29.029780.0055555555555555565/7207 6/28822-28823 28825 28827 28848-28849 28852https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/368/835?format=asciiX-raydefaultJ/A+A/368/835/table3The ROSAT PSPC Catalogue in the Galactic CenterNotesNotes (2)meta.notecharrecnoRecord number assigned by the VizieR team.
