Spectrum of object #20 (PSO J318.5-22, in black) along with the L7 young template (in red), L8 field template (in purple), and the spectrum of object #56 (SIMP J013656.5+093347.3, in gray), which was classified as T2 via a direct comparison with spectral templates. This comparison is shown to underline the significant change in the spectral morphology associated with the L-T transition. All spectra are normalized at 1.67 μm.
