Continuum emission at 5.4 μm obtained from line-free spectral channels in Channel 1 (left). Center: integrated emission of H₂ 0–0 S(7) line at 5.51 μm in colorscale. Right: integrated emission of [Fe II] line at 5.34 μm in color scale. Stars mark the MIR peak continuum position of the protostars. White circles show regions from which the spectra at the outflow positions were obtained, with diameters corresponding to two times the MIRI-MRS point-spread function (PSF) at 5.5 μm. In the bottom-left corners, MIRI-MRS empirical FWHM of PSF (Law et al. 2023) is indicated as a white circle.
