GIANO NIR radial velocity with red circles and HARPS-N optical RVs with blue circles. The best fit Keplerian model obtained from optical data is plotted with a solid black line. The top panel shows the RV data in function of the phase. The bottom panel shows the RV as a function of the time and the residuals information. The NIR radial velocities (in red) are in excellent agreement with the optical data (in blue).
