Fit of the observed Eu II 4129.70 Å and Eu II 4205.05 lines in HD 140283. Crosses: observed spectrum. Dotted lines: synthetic spectra computed for the abundances indicated in the figure (blue), only with the contribution of V abundance (green), and without Eu and V (red). Solid line: synthetic spectrum computed with the best suited Eu abundance (red) and with a minimum limit (green), also indicated in the figure.
