Abstract:
The calibration of the Radial Velocity Spectrometer (RVS) onboard the
ESA Gaia satellite (to be launched in 2012) requires a list of
standard stars with a radial velocity (RV) known with an accuracy of
at least 300m/s. The IAU commission 30 lists of RV standard stars
are too bright and not dense enough.
We describe the selection criteria due to the RVS constraints for
building an adequate full-sky list of at least 1000 RV standards from
catalogues already published in the literature.
Description:
Table 2 is the preliminary list of radial velocity standard stars
built for the calibration and zero-point of the Gaia Radial Velocity
Spectrometer (RVS). The stars are selected within the IAU Commision 30
lists of RV standards, and 3 catalogues available at CDS:
Nidever et al. (2002, Cat. J/ApJS/141/503);
Nordstrom et al. (2004A&A...418..989N 2004A&A...418..989N, Cat. V/117);
Famaey et al. (2005, J/A+A/430/165).
Table 2 provides: Hipparcos and corresponding HD/DM identifiers;
Hipparcos positions (J2000); Hipparcos photometric data (V, B-V, V-I);
Simbad spectral types; and corresponding RV data: from the IAU
Commission 30 RV standards, and from the 3 above catalogues: Nidever
(RV; time span), Nordstrom (RV, number of measurements, time span),
and Famaey (RV, number of measurements, time span).

Note (1): The Elodie and Coralie IAU RV standard stars lists are available at
http://obswww.unige.ch/~udry/std/std.html
Note (2): The numbers famnum and famDT were very kindly provided by B.
Famaey, as they are not published in Famaey et al. (2005, Cat.
J/A+A/430/165).
Note (3): The Main list (1342 stars) and Supplementary list (78 stars) are
described in the A&A article, Section 4.4. The stars in Supplementary
list have less good environment criteria than Main list, or sometimes
only 2 RV measurements when taken from the Nordstrom or Famaey Catalogues.
