TL;DR: In this paper, a preliminary spectral classification system for L and T dwarfs is presented based entirely on four spectral indices in the 1-2.5 μm interval, two of these indices are derived from water absorption bands at 1.15 and 1.4 μm, the latter of which shows a smooth increase in depth through the L andT sequences and can be used to classify both spectral types.
