Caption: Figure 8.

Relative strength of the 11.3 μm PAH feature (a normalized "line"-to-continuum ratio) vs. the hardness of the radiation field as expressed by the line ratio of [S iv]/[Ne ii]. Each data point corresponds to one pixel in the spectral map. Only those 42 pixels with a signal of greater than four standard deviations in the S iv map have been included.
