| Description |
Radial velocities are released here for 110,762 objects, 97% of the objects for which spectra were released in GAIAESO DR4. For GIRAFFE, Jackson et al. (2015) estimates in a 0.25 km s-1 the maximum achieved precision (function of SNR, stellar parameters, and vsini). A lower precision is achieved with UVES (0.32 km s-1), due to the lack of simultaneous calibration exposures.
