Effect of 9.8 μm silicate IS extinction feature. Top panels: fits to the SEDs and MIR spectra without IS extinction correction (AV = 0), bottom panels: fits for three stars with, from left to right, AV = 2.4, 4.3, and 5.7 mag, respectively. The luminosity and optical depth were refitted in the case of AV = 0 and that is the reason that the difference in the SEDs appears small.
