Pole orientations of Quaoar’s main body (α_p,δ_p), allowed by the occultation constraints, assuming an oblate spheroid shape with true oblateness values 0.11 ≤ ϵ ≤ 0.2 (see the colour bar). The black regions require ϵ > 0.20. The black star is the preferred pole solution of the Q1R ring (Pereira et al. 2023). The black dot and circle mark the pole solution of Weywot’s orbit by Pereira et al. (2023). The coloured dots and circles mark the Weywot orbital pole solutions by Fraser et al. (2013, red with highest probability). The black plus signs (+) mark the two pole positions used in our radiometric models: (α,δ) = (225°, + 70°) and (45°,−70°).
