FWHM measurements (top), RV measurements (middle), RV residuals from cycle and GP model (next bottom) and RV residuals from Keplerian model (bottom), of the ESPRESSO, HARPS, HARPS-N and CARMENES datasets using SHO (P_ROT and P_ROT/2) GP model (grey solid line) to describe the activity caused by stellar rotation and including a double sinusoidal model to describe the long-term cycle (red thick dashed line), and a Keplerian model (grey shaded area), and GLS periodograms (left) of GJ 699 (model L1 in Table 3 with prior and posterior parameters given in Table D.1). The uncertainties include the jitter term coming from the global model.
