MCMC corner plot for the basic 5-parameter fit (Sect. 5.3), highlighting the key correlations present in the data. Note that we treat ρ₀ as an arbitrary scaling factor. A clear correlation is observed between the disk inclination and characteristic radius, as is expected geometrically. The disk characteristic radius is also negatively correlated with the overall scaling factor ρ₀, which is a natural consequence of the 1 /d² scaling of scattered flux (see Equation 3).
