[Ce/Y] values for the 169 sample stars. The dots without error bars represent stars for which there are less than 3 lines for one of the elements. The solid line represents the weighed fit through the data points with [Fe/H] between solar and −0.8. The equation of the line is (−0.038 ± 0.021) + (−0.796 ± 0.087) × x. The dotted lines represent a spread of ±0.25 around the fitted line.
