Flux densities at the five different wavelengths predicted by the best-fit physical models using standard grains in the nonscattering and scattering case. The red and black dashed-dotted curve shows the models predictions at the radii where the flux at each wavelength was included in the fitting procedure (only fluxes larger than 3 times the rms error were considered at each radius). The grey curve shows the scattering model prediction at all radii.
