Fig. 4.


T eff vs. log(g) for the Ba sample. The thin disc (blue, 1476 stars), thick disc (red, 176 stars), and metal-rich α-rich (green, 42 stars) samples are shown. Different symbols are used for HARPS (•), FEROS (), and UVES (). We note that the coverage on this T eff vs. log(g) plane is similar to the Eu, Gd, and Dy sample, in addition to a different number of stars.
