Outcome of the fit of the three-planet model: The format of this figure is identical to that in Fig. 4, but isdescribed again here for convenience. (Top left) RV time series along with the best model (solid green line)that includes the planetary signals and best prediction from the GP stellar activity model. The 1 σ uncertainties from the GP prediction are also displayed (shaded green area). For this plot, we subtracted the systemic velocity and the instruments offsets from the RV data (see values in Table H.1). (Bottom left) Time series of the residuals of the best model. (Right) Zoom on a small portion of the time series to better visualize the short-timescale variations.
