The RVS spectrograph on board of Gaia having no calibration device, radial velocity standards are needed to calibrate the zero-point of the instrument. We have prepared a list of 2798 such stars, well distributed over the sky, and compiled ˜25 000 individual RV measurements from ground-based velocimeters. For a fraction of these stars, their stability at the 300 ms level during the Gaia mission has still to be assessed. The catalogue and follow-up programme are presented.Read less <
