Spin-spot misalignment model for CCW and Prot ~ 10.8 days.
| Parameter | Units | Prior | Posterior median and 1σ |
|---|---|---|---|
| Centre latitude | (°) | U(−90, 90) | 35.7 ± 1.4 |
| Centre longitude | (°) | U(−180, 180) | −33.3 ± 1.1 |
| Radius (spin-spot angle, Θ) | (°) | U(0, 90) | 5.64 ± 0.64 |
| Rotational period (Prot) | (days) | U(10, 12) | 10.8072 ± 0.0098† |
| Reference time‡ − 2 460 000 | (BJDTDB) | U(63.8, 85.4) | 66.90 ± 0.66† |
| Inclination of the spin axis, i⋆ | (°) | 47.3 ± 1.2 | |
| Sky-projected spin-orbit angle, λ | (°) | 37.3 ± 1.5 | |
| True spin–orbit angle, ψ | (°) | 54.3 ± 1.4 |
Notes. U(1,u): uniform distribution prior in the range [1, u]. † Multimodal, only the higher CCW posterior peak is shown. ‡ The position of the spot at the reference time is marked with a black dot in Fig. 3. Skyprojected and true spin-orbit angles are calculated based on the spin axis orientation and the orbital inclination.
