Notes. The parameters are the period, semi-major axis, eccentricity, inclination, longitude of node (mod 180°), argument of periastron passage (mod 180°), and time at periastron passage. The median value is the 50% value, the lower and upper values are the lower and upper bounds of the 68% interval, andthe 
value is the best-fit value.
