The catalogue of radial velocities of galactic stars with high precision astrometric data (CRVAD)

 Description:
    The catalogue of radial velocities of Galactic stars with high
    precision astrometric data (CRVAD) is the result of a merging of star
    lists from the General Catalog of Mean Radial Velocities (GCRV, Cat.
    III/213) and from the All-sky Compiled Catalogue of 2.5 Million Stars
    (ASCC-2.5, Cat. I/280). The cross identification of GCRV and ASCC-2.5
    objects was carried out with help of coordinate, magnitude, colour
    and/or spectral type criteria. Data from the Catalogue of Components
    of Double and Multiple Stars (CCDM, Cat. I/274) were taken into
    account for the identification of multiple system components. 34553
    stars of the ASCC-2.5 were identified with 33509 stars of the GCRV,
    i.e. 33509 stars of the GCRV have one entry in the ASCC-2.5, and 1044
    objects have two entries. The catalogue includes accurate equatorial
    coordinates J2000, proper motions and trigonometric parallaxes in the
    Hipparcos system, B and V magnitudes in Johnson system, spectral
    classes, multiplicity and variability flags from the ASCC-2.5, and
    radial velocities, stellar magnitudes and spectra from the GCRV. Stars
    are sorted in right ascension J2000 order.

    3967 stars were selected as radial velocity standard candidates (file
    rv_std.dat). These stars:
    - do not have any multiplicity and/or variability flags
      both in the GCRV and ASCC-2.5;
    - have standard errors of equatorial coordinates e <= 40 mas;
    - have standard errors of proper motions e_pm <= 4 mas/yr;
    - have standard errors of V magnitude e_V <= 0.05 mag
      and (B-V) colour e_(B-V) <= 0.07 mag;
    - have standard errors of radial velocity e_RV <= 2 km/s or
      quality index A or B, which corresponds to e_RV 0.74 and 1.78 km/s;
    - have at least four RV observations N_RV.
