Comparison between stars sub-classified into the CEMP-s/rs and CEMP-no categories using either the [Ba/Fe] or the A(C) criterion. As before, the blue and red colors indicate the CEMP-s/rs and CEMP-no stars, respectively. The left panels correspond to use of the [Ba/Fe] criterion, while the right panels are based on the A(C) criterion. That is, CEMP-no stars are classified as such if they have A(C) ≤ 7.1, while CEMP-s/rs stars are classified as such if they have A(C) > 7.1. There are 15 stars with upper limits on [Ba/Fe] < 0.0 not shown in this figure. A typical observational error bar is shown in the bottom left of each panel.
