Radial intensity profile comparisons between observations and best-fit RADMC-3D models. Gray horizontal dashed lines indicate the noise level (3σ). Gray vertical lines indicate the clump radius used in the modeling. The dotted line indicates beam shape in each plot. For source G18, G19, G08a, G13, and G31, the model fit after re-adjusting T(r) is shown. The gray vertical line indicates the clump radius R_clump.
