Notes. The listed parameters are sidereal rotation period P; spin-axis ecliptic J2000 coordinates λ and β; volume-equivalent diameter D; dimensions along the major axis of the best-fit triaxial ellipsoids (a > b > c); their ratios a/b, b/c, and a/c; and bulk density ρ using the mass given by the orbital multipole model (Table 2). Uncertainties correspond to 1σ values.
