SEW cloud in the light of molecular line and continuum emission. Top row (from left to right): CS(5–4), H¹³CO⁺(3–2), SiO(6–5), and SO(7–6) (all as in Fig. 5). Bottom – from left to right: C₂H(3–2) (as in Fig. 5), and ¹³CS(2–1), N₂H⁺(1–0), and CH₃OH(8–7) (all three as in Fig. 4). Contours show the CS(5–4) emission (as in Fig. 5), except from the top outer left, which shows contours of the 250 GHz continuum emission as in Fig. 2.
