VizieR Online Data Catalog: Main-sequence and subgiants ROSAT data (Huensch+ 1998)
Abstract
We present X-ray data for all main-sequence and subgiant stars of spectral types A, F, G, and K and luminosity classes IV and V listed in the Bright Star Catalogue (Cat. <V/50>) that have been detected as X-ray sources in the ROSAT all-sky survey; In addition to count rates, source detection parameters, hardness ratios, and X-ray fluxes we also list X-ray luminosities derived from Hipparcos parallaxes.
