Average dust optical depth of the LMC (black) and SMC (blue) obtained from the CMB, foreground and free-free subtracted SEDs. The average is taken in the same regions as Fig. 5. The SMC SED was normalised (multiplied by 6.31) to that of the LMC at 100μm. The square symbol (green) shows the reference value for the solar neighbourhood by Boulanger et al. (1996). The dashed lines show τ ∝ ν1.5 and τ ∝ ν1.2 normalised at 100μm. Error bars are  ± 3-σ.
