JWST/MIRI-MRS continuum-subtracted spectrum (blue) centered on the v₂ band of SO₂ around 19 µm. No clear emission or absorption features of SO₂ are detected. Overlaid are LTE slab models obtained using the best-fit parameters derived from the v₃ band around 7.35 µm (red) and the pure rotational lines in the ALMA data (green). The MIRI slab model is scaled down by a factor of 10⁻³ for clarity. Both models are offset with respect to the data and are corrected for an extinction of A_V = 55 mag (Rocha et al. 2024) using a modified version of the McClure (2009) extinction law (see Appendix C).
