Increase in [Ba/H] (top panel) and [Eu/H] (bottom panel) with [Fe/H] (red squares) from the low-metallicity bin I (−2.1 <  [Fe/H] ≤ −1.8) to more metal-rich bins: II (−1.8 <  [Fe/H] ≤ −1.5), III (−1.5 <  [Fe/H] ≤ −1.2), and IV (−1.2 <  [Fe/H] ≤ −0.9), as indicated with dotted gray lines. Open diamonds are the contributions to [Ba/H] from the r-process (green), and to [Eu/H] from the s-process (orange). The range of the y-axis is different in the two panels.
