Fits of the synthetic spectra to the observed lithium line at 6708 Å for the spectrum of HD 189627 (top) and HD 190125 (bottom). The contribution of the Fe I line at 6707.473 Å in the formation of the blend is clearly seen in both cases, and is particularly noticeable in the spectra of HD 190125. The used input parameters for these computations are given in Table A.3.
