cds-question@unistra.frmolecular-cloudsx-ray-sourcesinfrared-sourcesWe have obtained two deep exposures of the {rho} Oph cloud core region with the ROSAT High Resolution Imager. The improved position accuracy (1"-6") with respect to previous recent X-ray observations (ROSAT PSPC, and ASCA) allows us to remove positional ambiguities for the detected sources. We also cross-correlate the X-ray positions with IR sources found in the ISOCAM survey of the same region at 6.7 and 14.3{mu}m, in addition to sources (optical and IR) known from ground-based observations, which are young stars (T Tauri stars, with and without circumstellar disks, and protostars). We thus obtain the best-studied sample of X-ray emitting stars in a star-forming region (63 X-ray sources detected, and 55 identified).2000A&A...359..113Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/359/113CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/28 : ROSAT HRI Pointed Observations (1RXH) (ROSAT Team, 1999)Table 1: Log of ROSAT HRI Observations:https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/359/113https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/359/113http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/359/113https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/359/113https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/359/113http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/359/113GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/359/113/tablea1 (HRI X-ray sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/359/113/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/359/113/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/359/113/tablea1?GETtext/xml+votable180.050000true246.329167-24.4477780.0055555555555555566/42981 42983https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/359/113?format=asciiX-rayInfrareddefaultJ/A+A/359/113/tablea1HRI X-ray sourcesrecnoRecord number assigned by the VizieR team.
