Posterior distribution of Ω_★ (equivalently λ) and i_★, for a fit with fitting ranges 0° < i_★ < 180° and 0° < Ω_★ < 360°. A clustering analysis was performed on the posterior, dividing it into four groups, indicated with different colours. The median and 1σ uncertainties of each group are shown with the open circles and error bars. The red circle is the ‘correct’ solution. Contours indicating the density of the posterior space are shown with magenta lines.
