The PDFs of gas column density N(H) in diffuse regions (hatched red) derived from 7.7 μm intensities (Equations (13) and (14)) for each galaxy. Lognormal fits to each of the PDFs with the fit means are overlaid in black for comparison. The best-fit lognormal mean N(H) (μ N ) and dispersion (σ N ) are included, as in Table 2.
