Examples of the composite spectral templates produced from the median of several empirical spectra from the literature. The composite templates for late M and early spectral types with surface gravity indices γ and β are constructed by taking the median of several objects from the Montreal spectral library (Gagné et al. 2015; Robert et al. 2016). For T-types we construct median template spectra from known T-types in the SpeX Prism Library (Burgasser 2014) and the Sloan Digital Sky Survey (Chiu et al. 2006). The templates have typical resolution of Δλ ≈ 5−40 Å.
