Extinction curves for each region derived from the different dust models with a 60 Myr RF (left) and 600 Myr (right). The averaged Galactic and LMC extinction curves are plotted as black diamonds and dark gray crosses for comparison. The LMC2 supershell extinction curve is presented with light gray triangles. We caution that the scales have been chosen to show the difference between the different models in a clear way, and this must be taken into account in the comparisons.
