Notes. We provide the H2 excitation temperatures and column densities in Table 4. (1)foreground extinction; (2)internal PDR extinction calculated using the foreground formalism (see Fig. 14); (3)internal PDR extinction calculated using the intermingled formalism; (4)ratio of the integrated intensities of the (3.39+3.40+3.42)/(3.29) AIBs using the Gaussian decomposition method. (5)ΣAIB refers to the sum of all Gaussian AIB components in the 3.2–3.7 µm range.
