Corner plot of the posterior distribution and SED fit of a mock source at redshift z = 3.06. The posterior distribution shows dust parameter estimation using (i) GMBB-Sizes (green) and (ii) GMBB-Lambda (red), which are over-plotted with the true values in black. In this fit, λ_thick for GMBB-Sizes is estimated using Eq. (7) given the posterior distribution of the output parameters (β, M_dust and A), and M_dust distribution for GMBB-Lambda is also estimated with Eq. (7) using the posterior distribution of the output parameters (β, A = 4πR², and λ_thick).
