Three pure rotational transitions of H₂ from left to right: S(7) at 5.51 μm, S(3) at 9.66 μm, and S(1) at 17.04 μm. Integrated emission maps are created from the cubes after subtracting the local continuum. The positions of the protostars measured from the line-free region at 5 μm are shown with white stars. Maps are centered on the position of the TMC1-W source. The horizontal dotted line in the right panel indicates the cut for which different H₂ 0–0 S bands are shown in Fig. 6. The physical components of the system are illustrated in the middle panel. The disk wind is indicated based on H₂ S(7), CO outflow is based on the ALMA observations, and scattered light on the HST 1.6 μm image in Fig. 8. Bottom-left corners: MIRI-MRS empirical FWHM of PSF (Law et al. 2023) indicated as a white circle.
