Variable Sources: radial velocity time series (gaiadr3.vari_rad_vel_statistics)

The table has 1898 rows, 16 columns.

Description

Statistical parameters of radial velocity time series, using only transits not rejected, see rejected_by_variability column in vari_epoch_radial_velocity. Note that NaN will be reported when the parameter value is missing or cannot be calculated.
