LTE slab model fits (blue) of the ∼6.8–7.5 μm bending mode of water in the disks of GM Aur and J1615 (JWST-MIRI spectrum in black). Bright atomic and molecular hydrogen and other atomic and ionic emission lines are labeled with gray dashed lines. The horizontal blue lines are the fitting windows used to calculate χ² (see Appendix A). As stated in Section 3.1.1, the presence of water lines at these wavelengths in J1615 may indicate a water reservoir closer to the central star.
