Variable stars: Radial Velocity Statistics (gaiafpr.vari_rad_vel_statistics)
The table has 9614 rows, 16 columns.
Description
Statistical parameters of radial velocity time series using only transits retained and not rejected (see the relevant rejection flag in the epoch radial velocity variability table).Note that NaN will be reported when the parameter value is missing or cannot be calculated.
