Distribution of the underestimation factor and dust temperature in the parameter space of {F_{1.3 mm}, R_out}. Upper panel: Λ_{1.3 mm} asafunction of F_{1.3 mm} and R_out. Black dots stand for the DSHARP disks. The black star represents the DoAr 33 disk. Smooth disks and disks with substructures observed in Long et al. (2019) are indicated with gray dots and gray rings, respectively. All the flux densities are scaled to the distance of 140 pc. Bottom panel: T_dust as a function of F_{1.3 mm} and R_out. The dashed line draws the contour level of 24.8 K, which is the analytic temperature simply given by 25 (L_⋆/L_⊙)^0.25 K.
