Spectrum of IRAS2A in blue centered around the v₃ band of SO₂ as observed by JWST/MIRI-MRS. The local continuum fit is shown in red and the best-fit LTE slab model in orange at a +5 mJy offset. In green, the SO₂-subtracted data are presented, revealing the 7.4 µm ice absorption feature that was hidden by the P-branch of the SO₂ v₃ band. The Q-branch is slightly overfitted, resulting in a subtraction residual. The ice absorption bands are further analyzed by Rocha et al. (2024).
