Notes. P is the orbital period and Tperi the time of periastron passage, Vγi denote the systemic velocities, e the eccentricity, and ω the longitude of periastron. Ki are the semi-amplitudes of the RV curves, ai sin i the minimum semi-major axes, and Mi sin3i the minimum masses. The mass ratio is defined as q = M2/M1. The rms corresponds to the root mean square deviation. In all systems, the component with sharper spectral lines is defined as the primary.
