Synthetic spectrum fit to the lanthanum line at 4662 Å in the observed spectrum of HD 143291 (left panel) and to the neodymium line at 5319 Å in the observed spectrum of HD 24156 (right panel). The observed spectra are shown by solid lines with dots. The dotted lines are synthetic spectra with [La/Fe] = 0.05 ± 0.1 and [Nd/Fe] = 0.12 ± 0.1, respectively.
