Impact of the choice of number of components on the signal detection. The top panel displays the peak associated with the maximum period in the periodogram when the wPCA reconstruction is eliminated from the data using varying numbers of components. In the middle panel, the logarithm of the FAP linked to this signal is presented, while the bottom panel depicts the log BF evaluating the significance of a 14.2 d Keplerian signal compared to an offset. The black and red data points correspond, respectively, to the outcomes obtained from the pre-and post-outlier rejection RV time series.
