Results of the elliptical limb fitting.
| Parameter | Original chords(a) | Aligned chords |
|---|---|---|
| Semi-major axis a′ (km) | 292 ± 3 | 293 ± 3 |
| Semi-minor axis b′ (km) | 231 ± 6 | 230 ± 6 |
| Oblateness e' = (a′–b′)/a′ | 0.21 ± 0.03 | 0.21 ± 0.03 |
| Tilt angle (°) | −11 ± 2 | −6±2 |
| (fc, gc) (km)(b) | (−1010 ± 2,770 ± 5) | (−1007 ± 2,769 ± 5) |
| (ƒc, gc) (mas)(b) | (−38.57 ± 0.09, 29.40 ± 0.19) | (−38.43 ± 0.09, 29.37 ± 0.17) |
| Area-equivalent diameter (km) | 519 ± 10 | 519 ± 10 |
| Mean area-equivalent diameter (km) | 545 ± 13 | 545 ± 13 |
| Geometric albedo pV | 0.134 ± 0.010 | 0.134 ± 0.010 |
Notes. The nominal values were obtained by minimization of a least squares function and the uncertainties are the standard deviation of the Monte Carlo distributions, see Sect. 4.1. The corresponding distributions can be seen in Appendix B. The uncertainty bars of the equivalent diameters and albedo were obtained analytically from their respective mathematical expressions. (a)Chord 8 is the only chord that has been shifted for this case, see Sect. 4.1. (b)Offsets with respect to the JPL #33 orbit.
