a), c), and e) surface brightness maps of [N ii] at 1461 GHz, CO (J = 5–4), and OH⁺ at 971.8 GHz, respectively. The contours of these maps are overlaid on the SPIRE 250 μm image: b), d), and f), respectively. g) shows the image of the surface brightness of [C i] (2–1), and h) shows the contours of the [C i] (2–1) intensity distribution overplotted on the OH⁺ 971.8 GHz map. All the maps are centered at RA(J2000) = 22^h29^m16.3^s, Dec(J2000) = −20°50′25.96′′. The maps are resampled with a scale of 6′′/pixel.
