Best-fit synthetic spectra for all targets using the SM08 models (blue) and Sonora Diamondback (red) models, overlaid with the observed IRTF/SpeX spectra (black). Fluxes within the broad water bands (shaded in gray) are masked in spectral fits. Targets are ordered by spectral types, spanning M7–T8.
