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