VizieR Online Data Catalog: NEXXUS ROSAT survey of coronal X-ray (Schmitt+, 2004)

We present a final summary of all ROSAT X-ray observations of nearby stars. All available ROSAT observations with the ROSAT PSPC, HRI and WFC have been matched with the CNS4 catalog of nearby stars and the results gathered in the NEarby X-ray and XUV-emitting Stars (NEXXUS) data base. New volume-limited samples of F/G-stars (table 1), K-stars (table 2), and M-stars (table 3) are constructed within which detection rates of more than 90% are obtained.
