Top: Daily binned RVs and 30 day smoothed average once a linear fit to the Mg2 activity index has been removed to mitigate the RV long-term effect induced by the solar magnetic cycle. Bottom: Corresponding Lomb-Scargle periodograms in RV amplitude. As can be seen, the 30 day smoothing absorbs signal up to 150 days and both datasets give the same signals above 150 days. The horizontal dashed line corresponds to the maximum peak for periods longer than 150 days, which is seen at a period 895 days, with an RV amplitude of 0.21 m s⁻¹. The numbers on top of each significant peak, highlighted in grey, correspond to the signal false alarm probabilities.
