We present a catalogue of radial velocities of Galactic stars with high precision astrometric data CRVAD which is the result of the cross-identification of star lists from the General Catalog of Average Radial Velocities (GCRV) and from the homogeneous All-sky Compiled Catalogue of 2.5 Million Stars (ASCC-2.5). The CRVAD includes accurate J2000 equatorial coordinates, proper motions and trigonometric parallaxes in the Hipparcos system, Johnson's BV photometric data, spectral types, multiplicity and variability flags from the ASCC-2.5, and radial velocities, stellar magnitudes and spectral types from the GCRV for 34553 ASCC-2.5 stars. The CRVAD was used for the construction of a sample of standard stars with accurate astrometric, photometric and radial velocity data for the RAVE project. A second application of the CRVAD , the radial velocity determination for 292 open clusters (including 97 with previously unknown radial velocities), using their newly defined members from proper motions and photometry in the ASCC-2.5, is briefly described.
