Statistical parameters of FOV time series (gaiadr1.phot_variable_time_series_gfov_statistical_parameters)

The table has 3194 rows, 16 columns.

Description

Statistical parameters of field-of-view time series, only including observations with rejected_by_variability_processing=false as found in the phot_variable_time_series_gfov table. Note that only sources that have phot_variable_flag = "VARIABLE" in the gaia_source table are included.
