Notes. 

(a)

Method for Teff determination: sp ... spectroscopic (excitation equilibrium of iron line abundances), ph ... photometric calibrations.

(b)

Method for log g determination: sp ... spectroscopic (ionization equilibrium of iron line abundances), ph ... photometric calibrations, ev ... from absolute magnitudes and stellar evolution calculations, li ... from literature.

(c)

α Tau was used as a reference object for the spectroscopic analysis of M giants.

(d)

from infrared spectra.
