Examples of Ba II (left) and Y II (right) lines in the spectra of two red giants with [Fe/H]NLTE = −1.65 (top) and [Fe/H]NLTE = −0.77 (bottom). The red shaded area represents the spectral range over which the line is fitted. The orange curve corresponds to the best line-fit. The black vertical corresponds to the central wavelength of the line.
