Left panels: median SEDs of Class II ETBDs (upper) and LTBDs (lower) in the Taurus molecular cloud. The dots depict the median flux densities at various bands. The upside down triangles show that the median flux densities at the corresponding wavelengths are treated as upper limits. The best-fit models are indicated with solid lines, whereas the dashed lines mark the photospheric emission levels. In the fitting procedure, the disk scale height H₁₀₀ and inclination i are fixed to 14 AU and 45°, respectively. The parameter set of the best model in the upper panel: R_in = 0.09 AU, M_disk = 3 × 10^-5 M_⊙, β = 1.16. The parameter values of the best model in the lower panel: R_in = 0.03 AU, M_disk = 5 × 10^-6 M_⊙, β = 1.14. Right panels: 2D contour plots of the χ² function projected over disk mass M_disk and flaring index β. Contours with different shades of red are drawn at the 68%, 90%, 95% 2D confidence intervals. The blue stars represent the best-fit disk models. The hashed regions correspond to models that overpredict the upper limits of the median flux density.
