Variability time series statistics (gaiadr2.vari_time_series_statistics)
The table has 550737 rows, 44 columns.
Description
Statistical parameters of time series, using only transits not rejected, see {rejectedByVariability} column in the VO Table {epochPhotometryUrl} in {gaiaSource}.
Note that NaN will be reported when the parameter value is missing or cannot be calculated.
