cds-question@unistra.frlate-type-starsx-ray-sourcesWe present X-ray data for all entries of the Third Catalogue of Nearby Stars (Gliese and Jahreiss, 1991, Cat. <V/70>) that have been detected as X-ray sources in the ROSAT all-sky survey. The catalogue contains 1252 entries yielding an average detection rate of 32.9 percent. In addition to count rates, source detection parameters, hardness ratios, and X-ray fluxes we also list X-ray luminosities derived from Hipparcos parallaxes.1999A&AS..135..319Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/135/319CatalogResearchIsServedByTAP VizieR generic servicerelated-toV/70 : Nearby Stars, Preliminary 3rd Version (Gliese+ 1991)IX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1996)J/A+AS/127/251 : Giants and supergiants ROSAT data (Huensch+ 1998)J/A+AS/132/155 : Main-sequence and subgiants ROSAT data (Huensch+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/135/319https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/135/319http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/135/319https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/135/319https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/135/319http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/135/319GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapROSATX-raydefaultJ/A+AS/135/319/table2RASS detections of the Gliese starsrecnoRecord number assigned by the VizieR team.
