Spectral energy distributions for two sources: G159.02-33.88 (top) and G195.90-02.60 (bottom). In each panel, the solid black line shows the best-fit model, with χ_red² = 0.8 and 0.7, respectively. Individual realizations from the converged MCMC chain, illustrating model scatter, are shown in blue. Color-corrected flux densities are plotted as orange points, with hollow markers indicating data points excluded from the fit due to residual CO contamination or excessively high frequencies. Each individual best-fit model component is displayed in gray, with the dotted line representing the AME component. The lower sub-panels display residuals in units of statistical deviation from the fit, with the 1σ region shaded in light blue.
