Abundance ratios between La and Eu as a function of [Eu/H] (left panel), [La/Fe] (middle panel), and [Fe/H] (right panel). Cepheid stars (filled circles) are compared with Galactic field dwarfs (crosses) and giants (open circles) by S04, with field dwarfs by FG98 (open triangles), and with Sgr field stars studied by McWilliam & Smecker-Hane (2005, MS05, filled triangles) and by McWilliam et al. (2013, M13, red stars).
