[Y/Fe] vs. [Fe/H] similar comparison samples as in Fig. 8, but also including a fourth sample – Roederer (2009, R09i/o) – shown as blue/purple open diamonds indicating stars belonging to the inner/outer halo, respectively. The enhanced stars agree with the other comparison samples as well as our sample. However, CS 31082–001 is seen to be particularly enhanced in Y. [Y/Fe] shows almost no variation with metallicity down to [Fe/H]  ~  −2.5 dex.
