Caption: Figure 8.

Difference between intrinsic and observed FUV luminosities vs. the observed WISE 22 μm luminosities. The black line shows the expected relation if a_corr was constant and equal to 3.89 for all regions. Most points lie above or below this line, showing that a constant value of a_corr mostly over- or under-corrects for the effect of the 22 μm derived extinction. Region 2 was not detected at 22 μm.
