Notes. Reported parameters are as follows: orbital period P, semimajor axis a, eccentricity e, inclination i, longitude of the ascending node Ω, argument of pericenter ω, time of pericenter tp. The number of observations and RMS between the predicted and observed positions are also provided. Finally, we report the mass of Pulcova MPulcova, the ecliptic J2000 coordinates of the orbital pole (λp, βp), the equatorial J2000 coordinates of the orbital pole (αp, δp), the orbital inclination (Λ) with respect to the equator of Pulcova, and Pulcova’s bulk density (ρ). Uncertainties are given at 1σ.
