Left: Comparison of RVs from HARPS-N extracted with ARVE (blue) and with YARARA (red), and RV SOAPv4 simulations based on the MM method both for spots and plages (SOAP with MM). Middle: RV time series from HARPS-N ARVE (blue) and YARARA (red) and from SOAP with MM (yellow; top), together with the residuals, calculated as the difference between observed and simulated RVs and their std value (bottom). Right: Histogram of the residuals between SOAPv4 RVs and ARVE (blue) and between SOAPv4 RVs and YARARA (red).
