RV based analysis for the simulated periodically active planet-hosting star. Upper panel: RVs obtained for the spectra through cross-correlating against a PHOENIX template. The RVs are phase-folded according to the planetary period. The blue bar stands for the mean difference between true and extracted RV. Lower panel: GLS periodogram for the RV data. The dashed vertical lines mark the expected activity and planetary frequency, matching 7 and 25 days period.
