Parameter correlations and distributions for MgSiO₃ for the selected models that satisfy the criteria of reduced chi-squared (χ_red² < 1.36) at the 3σ confidence level with a normalised intensity tolerance of ΔFW_limit = ±30%. The diagonal panels show the marginal distributions of the six parameters: log₁₀(a₀) (dust grain size in microns), log₁₀(ρ₀) (dust density at r₀ = 180 R_⊙ in g/cm³), p_ρ (density power-law exponent), and stellar radii (R_λ1, R_λ2, R_λ3) in solar radii for the wavelengths 0.65, 0.75, and 0.82 microns, respectively. Vertical and horizontal dashed lines in the histograms represent the median parameter values, and shaded regions indicate parameter ranges. The off-diagonal panels display pairwise scatterplots of the parameters, with denser regions indicating higher model density.
