cds-question@unistra.frglobular-star-clustersx-ray-sourcesWe present X-ray observations of ten globular clusters observed with the ROSAT PSPC. The clusters were chosen to have large core radii and to be nearby. Three clusters contain X-ray sources which are probably associated with the cluster. One is the previously discovered X-ray transient H1825-331 in NGC 6652. The other two, in NGC 6366 and NGC 6809, are new members of the class of low-luminosity sources, with luminosities in the region of 10^32^erg/s. Upper limits can be placed on the source temperatures of both sources, making them similar to sources found in other globular clusters by ROSAT.1996A&A...309..116Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/309/116CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/309/116https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/309/116http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/309/116https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/309/116https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/309/116http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/309/116GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/309/116/table2 (Detected sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/309/116/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/309/116/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/309/116/table2?GETtext/xml+votable180.050000true154.432917-45.9872220.005555555555555556ROSAT6/30299 30321 30380 30995 30998 31018-31019 31104-31105 38465 38468 41505 41507 41510 41513 41516 42275-42276 42278 42309 42320-42321 42955 42958 47754 47778 47866 47970-47971https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/309/116?format=asciiX-raydefaultJ/A+A/309/116/table2Detected sourcesrecnoRecord number assigned by the VizieR team.
