Lomb-Scargle periodograms of the RV time series based respectively on the observed (black solid line) and simulated (red solid line) activity patterns, alongside the 1% false-alarm probabilities (FAP, dashed lines). Top: spot+facula contribution. Bottom: sum of all contributions. We note that in both panels the periodograms corresponding to the simulations are vertically shifted for visibility. The solar rotation period and its two first harmonics are shwon in blue (solid, dashed and dash-dotted blue lines).
