Top panel: radial velocities of HD 22532 from CORALIE (COR98 in blue, COR07 in orange and COR14 in green) withthe best Keplerian model superimposed (solid line), and corresponding residuals around the solution. Second panel: phased radial-velocity solution. Third panel: periodograms of the radial-velocity time series, the residuals of the radial-velocities after substraction of the fit periodic signal, and the periodiodogram of the Hα activity index time series. The red vertical line indicates the period of the orbital solution (872.6 days). Horizontal lines are the FAPlevels at 10% (continuous), 1% (dashed), and 0.1% (dotted-dashed).
