Notes. All the other columns refer to the results obtained using NIR spectral indices, as explained in Appendix B. SpT are reported only in the range of validity of each index.
SpT derived in this work as explained in Sect. 3.1.
Results obtained using the spectral indices in the VIS part of the spectrum, as explained in Sect. 3.2.
