Comparison of the spectral type (left) and extinction A _J (right) determined with our template fitting, with the average spectral type given in K. L. Luhman et al. (2016). Spectral types are coded as a linear scale, M5 is 5.0 and L2 is 12.0. The orange line marks the 1:1 relation, the shaded region corresponds to errors of 1 spectral subtype and 1 mag in J-band extinction. For two objects (blue points), we show two possible solutions (joined with dotted–dashed lines); based on magnitudes and colors, the solution with late-M spectral type is preferred.
