MIRI-MRS spectra from the outflow positions. Spectra were continuum subtracted using a spline fit to line-free regions. The H₂ transitions are shown in purple, the hydrogen recombination line in yellow, and fine structure atomic lines in green. Top: TMC1-W jet (red) and TMC1-E wind (blue). Bottom: TMC1-E wind spectra. OH catalog emission line positions are shown as black markers (Yousefi et al. 2018; Tabone et al. 2021). Insets: [Co II] 10.521 μm, HCO⁺ 12.069 μm, and CO₂ 14.98 μm lines identified in the spectra. Flux in the insets converted to mJy.
