Description:
For the detailed statistical analysis of the X-ray emission of hot
stars we selected all stars of spectral type O and B listed in the
Yale Bright Star Catalogue and searched for them in the ROSAT All-Sky
Survey. In this paper we describe the selection and preparation of the
data and present a compilation of the derived X-ray data for a
complete sample of bright OB stars.
