Comparison between model and observed 890 μm continuum intensity profiles for the ten sources in our sample. For each source, the left panel shows the intensity profile and the right panel shows the matching normalized curve of growth for both the model (black, dashed) and the observation (colored, solid). Vertical lines in the right panels show the radius that encloses 90% of the total flux (R_{890 μm}). We note that the curve of growth of the model and the observation are normalized separately as the total flux is unimportantwhen measuring R_{890 μm}.
