Description:
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.
