Spectrum (top panel) and continuum images at various wavelengths (bottom row) of IRAS 2A. In the top panel, four insets are presented: around the SO₂ v₃ asymmetric stretching mode (~7.35 µm), SO₂ v₁ symmetric stretching mode (~8.7 µm), SO₂ v₂ bending mode (~19 µm), and CO₂ v₂ bending mode (~15 µm). In the latter, the emission originates mostly from the outflow (see Fig. B.1). The 12 sub-bands of the MIRI-MRS spectrum are not stitched and show minor offsets in overlapping wavelengths (see, e.g., the inset on the SO₂ v₁ symmetric stretching mode). The bottom row shows, from left to right, the dust continuum around 5.3 µm, 8.1 µm, 12.5 µm, and 19.3 µm; a sqrt stretch has been used to enhance fainter features without over-saturating bright emission. The open white circle indicates the size of the aperture from which the spectrum was extracted (i.e, 1.1″, 1.5″, 2.1″, and 3.0" in diameter at 5.3 µm, 8.1 µm, 12.5 µm, and 19.3 µm, respectively), which increases as a function of wavelength with the increase in the size of the PSF. A scale bar is displayed in the bottom left of each panel, and the size of the PSF is presented as the filled white circle in the bottom right.
