Numerical spectral type vs. the value of the spectral index for six different spectral indices, showing M0–M8 dwarfs (triangles) and M9–L8 dwarfs (plus signs). The lines are second‐order polynomial, least‐squares fits, with the dotted lines applicable for types M0–M8 and the solid lines applicable for types M9–L8. The VO7434 fit applies only through type L6 as described in the text.
