Posterior distributions for parameters of model described in Sect. 3.3 and Appendix A for Ω = θ_int ± 10°. Diagonal panels: distributions of model parameters. The blue solid, green dashed, and red dot-dashed lines correspond to per-passband B, V, and R distributions, respectively. Lower-triangle panels: joint posterior distributions of two parameters. The green, blue, and violet contours correspond to 0.68, 0.95, and 0.997 probability levels of parameters i, Ω, λ_p, and ϕ_p. The shades of blue, green, and red correspond to the same probability levels for B, V, and R filters, respectively.
