Test on the change of the FAP level of the peak on the peri-odogram at 6 days as a function of the number of visits for 100 randomly selected time series. The FAP level of the Ρ = 6 days peak decreases as a function of the number of measurements, as expected for a planetary origin of the signal. The random time series were sampled from the |V_tot| > 10 km s^–1 RV time series. The FAP level in this test was calculated using the analytical approximation implemented in pyAstronomy (Czesla et al. 2019).
