Same as Figure 22 but for the heavier elements. The [Cr/Fe] ratios demonstrate both the high precision we achieve in our abundances and the effects of S/N ratio on their determination. Points in orange (S/N < 100) have more than twice the rms scatter as those in blue (S/N ≥ 100). We have excluded iron from the comparisons since this would result in an uninformative flat line.
