Notes. The 16th, 50th, and 84th percentiles are denoted by P16, P50 and P84. As the values of the longitude of the ascending node (Ω) and argument of periapsis (ω) are not fully constrained by the radial velocity measurements, we present these values both over the full range (0–360°) and the restricted range usually quoted for astrometric orbits (0–180°). * The probability distribution for ω is multimodal and is highly correlated with other parameters.
