H₂O ν₂ = 1 − 0 band in IRAS 07251−0248 observed with JWST MIRI/MRS. Panels a and c show the observed spectrum, with the orange line indicating the adopted continuum level and the light-blue curve showing the contribution from the warm component. Panels b and d show the continuum normalized spectrum, with the blue line showing the model result for the hot component and the dashed line indicating its covering factor (f_hot). We label the main transitions that potentially contribute to the H₂O band as shown in González-Alfonso et al. (2024), but some very highly-excited lines are not detected in IRAS 07251−0248. Note that all H₂O absorption features are blueshifted relative to the labels.
