Fig. 2
Upper panel: fit of the observed Fe I 4154.806 Å line in HD 140283. Crosses: observations. Dotted blue lines: synthetic spectra computed for the abundances indicated in the figure. Solid red line: synthetic spectrum computed with the best abundance, also indicated in the figure. Dotted red line: residual value. Lower panel: plot of individual FWHM values for each of the 29 Fe I lines as a function of the equivalent widths. Dashed red line: average value FWHM = 6.38 km s-1.
