Comparison between the 17 μm H₂O luminosity and the spectral index n_13–25 (left), the stellar mass (middle) and the stellar luminosity (right) of the XUE disks with the Spitzer sample studied by Banzatti et al. (2020) shown with black squares (M < 2 M_⊙) and blue pentagons (M > 2 M_⊙) and the MIRI observations of nearby disks from the MINDS collaboration (Gasman et al. 2025). The measurements for the XUE spectra are shown with the colored circles, following the same color scheme as the rest of the paper with arrows showing the upper limits. The upper limits from Banzatti et al. (2020) are indicated with gray arrows. The MINDS sources are shown as magenta diamonds.
