Observed and predicted spectra of M5.5 dwarf GJ 1002 in Ti i (upper plot) and selected FeH lines (lower plot). Model parameters: T_eff = 3100 K, log g = 5.0, [M/H] = 0.0, υsini = 2.5 km s^-1. Observations are shown by thick solid line. Theoretical spectra were computed assuming ε_Fe =  −4.37 (red solid line) and ε_Fe =  −4.59 (blue dashed line) respectively. Wavelengths are in vacuum.
