cds-question@unistra.frlate-type-starsx-ray-sourcesTable 1 lists near-simultaneous X-ray data and Ca II H&K line-core emission data from the ROSAT All-Sky Survey and from the Mt. Wilson H&K spectrometer, respectively. The stars in this sample are 215 bright F-, G-, and K-type stars. Table 2 lists the derived excess Ca II H&K line-core and the X-ray flux densities for the same stars.1997A&A...325.1115Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/325/1115CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/325/1115https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/325/1115http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/325/1115https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/325/1115https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/325/1115http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/325/1115GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapX-raydefaultJ/A+A/325/1115/table1X-ray and Ca II datarecnoRecord number assigned by the VizieR team.
