RV time series with the best model fit (GP+1p). Panels a and b show the RV time series with the best GP+1p model. Panel c shows the GLS periodogram of the raw RV data. Panels d and e show the RV data detrended from stellar activity (i.e. planetary component). Panel f shows the GLS periodogram of the detrended RV time series. Panels g and h show the RV data detrended from the planetary component (i.e. stellar activity). Panel i shows the GLS periodogram of the activity-induced RVs. Panels j and k show the residuals after the fit. Panel i shows the GLS periodogram of the residuals.
