[Pd/Fe] (upper panel) and [Ag/Fe] (lower panel) vs. [Fe/H]. Red, green, and blue points represent thin disk, thick disk, and halo stars. Solid points denote dwarfs, while open circles denote the three giants in our sample. The arrows represent the lower or upper limits of the data points. The typical errors (see Sect. 5.1) are shown in the upper left corner of each panel. The dwarfs in Hansen et al. (2012) are also plotted as crosses in this figure.
