Top plot: time series of the activity indicator based on the Hα line extracted from the HARPS and HARPS-N spectra. Here, only the dataset of the third season is shown. Middle plot: GLS periodogram of the dataset is shown. The green line corresponds to the window function of the measurements, which is shifted in frequency so that the peak superimposes to the major peak of the RV periodogram, to directly identify possible alias frequencies. Bottom plot: time series phase-folded at the period P = 43.5 days.
