摘要：We present a new catalog of 18080 radial velocity (RV) standard stars selected from the APOGEE data. TheseRV standard stars are observed at least three times and have a median stability (3σ RV ) around 240 m s −1 over atime baseline longer than 200 days. They are largely distributed in the northern sky and could be extended to thesouthern sky by the future APOGEE-2 survey. Most of the stars are red giants (J − K s 0.5) owing to theAPOGEE target selection criteria. Only about 10 per cent of them are main-sequence stars. The H-band magnituderange of the stars is 7–12.5mag with the faint limit much fainter than the magnitudes of previous RV standardstars. As an application, we show the new set of standard stars to determine the RV zero points of the RAVE, theLAMOST, and the Gaia-RVS Galactic spectroscopic surveys.
