Spectral fitting of the 6437.640 and 6645.135 Å EuII lines for four sample stars. Red lines correspond to spectral syntheses with the abundance for Eu listed in Table A.1. Blue and green lines represent syntheses with abundances deviating by ±0.3 dex from the adopted abundance. The magenta line corresponds to the synthesis with a null abundance for Eu.
