Synthetic fit to Be lines in stars BS 16968-061 (top left), G 64-12 (top right), BD+03 740 (bottom left), and BD+09 2190 (bottom right). Each of the Be lines was fit separately. The best fit is shown together with spectra where the Be abundance was changed by ±0.1 dex. To aid in the visualisation, when necessary, some spectra are only shown in half of the panel.
