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.
