Time series of the RVs of ESPRESSO (in red) and PFS (in orange) together with the best fit model (in green) with five planets and GP to account for stellar activity (left panel). We show the 1 σ uncertainties from the GP model in shaded green. The systemic velocity and the offset between the two instruments was corrected. The residuals of the best model are shown in the bottom panel. Zoom of the left panel is shown on the right, displaying the middle season of observations when the ESPRESSO and the PFS observations overlap.
