Notes. Columns 2–5 give spectral types from indices by Herczeg & Hillenbrand (2014). The index JTiO 7140 is listed for comparison (Jeffries et al. 2007); however, it is not used in the final classification. The validity range of each spectral index is indicated in parentheses. The last column shows the adopted spectral type in this work (see Sects. 3.1 and 3.3 for details).
