Best-fit model (magenta) to the GHOST spectrum of AF Lep A (cyan), shown for (Left) the blended O I line at 7771–75 Å and (Right) the blended S I feature at 6757 Å. The residuals between the data and the model are plotted in black and other noise limits are shown in gray. Fitting the MARCS-C/O grid to the O I triplet feature gives a best-fit ﹩\mathrm{log}{\epsilon }_{O}﹩ = 9.06. After applying NLTE corrections, we get ﹩\mathrm{log}{\epsilon }_{O}﹩ = 8.84. The MARCS-C/S grid fit to the S I spectral feature gives a best-fit ﹩\mathrm{log}{\epsilon }_{S}﹩ = 7.12.
