Evolution of the measured semi-amplitude of every detected signal as a function of the number of measurements (left panel) and the date of the observations (right panel), using a double-sinusoidal model as in Sect. 4.2. Green filled dots, green empty dots, and blue filled dots show the HARPS pre-upgrade, HARPS post-upgrade, and HARPS-N measurements, respectively. The vertical black dashed line shows the moment at which each signal crosses the 1% FAP threshold. The grey dashed lines show a linear fit to the evolution of the PSD after the signals cross the 1% FAP threshold.
