Baade/MagE spectrum of TOI-5799 (black line) in comparison with the M2 SDSS template from Bochanski et al. (2007, magenta line). The spectra are normalized at 7400 Å, and prominent spectral features between 4300–8100 Å are labeled, including the regions affected by uncorrected telluric oxygen and water absorption (⊕). The 6555–6585 Å region is shown in the inset to highlight the Hα and Ca I features.
