Zoom-ins of the CX Tau spectrum (black) at the locations of the eight pure-rotational H₂ lines in the MIRI/MRS wavelength range. We show the best-fit ro-vibrational H₂O model (the best fit to the 5.5-8.5 µm region) in all panels containing lines below 10 µm and the best-fit rotational model (the best fit to the 13.5-17.5 µm region) in all panels containing lines at longer wavelengths. These H₂O slab models are shown in blue.
