Description:
    The cross-correlation of the source list from the ROSAT All-Sky Survey
    with the 5 GHz Green Bank survey yields a list of 2127 objects. About
    two thirds of them are optically unidentified. The majority of the
    objects with known optical counterparts are quasars and radio
    galaxies, most of them detected in X-rays for the first time. In this
    paper we present a list of the previously optically identified objects
    with their main characteristics and discuss their general (bulk)
    properties. We find strong correlations between luminosities in the
    radio, optical, and X-ray bands which differ for quasars and radio
    galaxies.
