Left panel: composite image of [C II]﹩\lambda 158\,\mu {\rm{m}}﹩ intensity (red, normalized to 3.8 × 10⁻⁷ W m⁻² sr⁻¹), [O I]﹩\lambda 145\,\mu {\rm{m}}﹩ (green, 6.4 × 10⁻⁸ W m⁻² sr⁻¹), and [O I]﹩\lambda 63\,\mu {\rm{m}}﹩ (blue, 9.4 × 10⁻¹¹ W m⁻² sr⁻¹). Middle and right panels: respective images of derived log(n_H) (m⁻³) and log(G/G₀) (G₀ in Habing 1968 units, 1.6 × 10⁻⁶ W m⁻²), computed by localizing FIFI-LS line intensities/ratios on the PDRT parameters. Contours in all of the panels are the same as in Figure 1.
