cds-question@unistra.frx-ray-sourcesmagellanic-cloudssurveysAbout 200 X-ray sources from a sample of spectrally hard ROSAT PSPC sources, given in the catalog of Haberl & Pietsch (1999, Cat. <J/A+AS/139/277>), and observed in a ~60 square degree field of the LMC during several archival pointed observations with a wide range of exposure times have been reanalyzed. For these sources accurate count rates and hardness ratios have been recalculated. In comparison to Haberl & Pietsch (1999, Cat. <J/A+AS/139/277>) we used merged data from all available observations and we derived average source parameters by investigating each source individually. From a simulation power-law spectral tracks have been derived in the HR1-HR2 plane and ~170 sources have been classified as background X-ray sources or as LMC X-ray binaries. 80% of the spectrally hard X-ray sources with more than 50 observed counts have been found to be consistent with background X-ray sources and 20% with LMC X-ray binaries (53 sources with AGN and 15 with X-ray binaries).2002A&A...388..100Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/388/100CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/139/277 : LMC X-ray sources ROSAT PSPC catalogue (Haberl+, 1999)J/A+AS/143/391 : ROSAT HRI catalogue of LMC X-ray sources (Sasaki+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/388/100https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/388/100http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/388/100https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/388/100https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/388/100http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/388/100GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/388/100/table3 (List of 97 ROSAT PSPC X-ray sources in the northern region of the LMC Supergiant Shell LMC4)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/388/100/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/388/100/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/388/100/table3?GETtext/xml+votable180.050000true81.053333-66.3480560.0055555555555555565/8278 6/33116-33118https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/388/100?format=asciiX-raydefaultJ/A+A/388/100/notesNotes to table 1recnoRecord number assigned by the VizieR team.
