Notes. The table includes: periastron time (TP, derived from the fit), inferior conjunction time (TC, measured through the fitting process), orbital period (P), , , orbital eccentricity (e), argument of periastron (ω), RV semi-amplitude (K) and the HARPS-N zero point correction (γHARPS−N). The minimum planetary mass (Mpsini) and the semi-major axis (a) are also derived.
