Spitzer spectral maps of the H₂ rotational transitions around SMM3 (upper panels) and SMM4 (lower panels), which are resampled on the PACS footprint pattern. The 0–0 S(0) and S(1) transitions show diffuse emission. Higher energy transitions display the outflow pattern as in the case of CO and H₂O, except for SMM4 where the extension to the north is only traced in [OI] (see Fig. 12). Contours start at 10^-14 erg cm^-2 s^-1 and increase by 10^-14 erg cm^-2 s^-1 steps.
