Notes. The orbital solution is computed from 129 RV measurements (listed in the appendix). T0 refers to the periastron passage. γ, K and asini denote the apparent systemic velocity, the semi-amplitude of the radial velocity curve and the projected separation between the center of the star and the center of mass of the binary system.
