Notes. Orbital period P, semi-major axis a, eccentricity e, inclination i, longitude of the ascending node Ω, argument of pericentre ω, time of pericentre tp, ecliptic J2000 coordinates of the orbital pole (λp, βp), and equatorial J2000 coordinates of the orbital pole (αp, δp). The number of observations and RMS between the predicted and observed positions are also provided. Uncertainties are given at 1-σ.
