Same as Figure 7 but the best-fit-intensity radial profiles of the 1D models are indicated by the dotted lines at each wavelength. The light-blue and dark-blue lines corresponds to the models with the τ < 1 at 8.9 mm and without, respectively. The data and best-fit MCFOST models at 1.3 mm and longer were convolved to the resolution of the 0.9 mm image to match the resolution of the slab models.
