Synthetic spectrum fit to the praseodymium line at 5323 Å in the observed spectrum of HD 3795 (left panel) and to the samarium line at 4467 Å in the observed spectrum of HD 22872. The observed spectra are shown by solid lines with dots. The dark grey solid lines are synthetic spectra with [Pr/Fe] = 0.54 ± 0.1 and [Sm/Fe] = 0.01 ± 0.1, respectively.
