Fig. 4

Spectral synthesis for four thin disk stars in our sample. From top to bottom: HD 33632, HD 186379, HD 100180, and HD 94835. Solid dots represent the observed spectra with Keck/HIRES, and the solid lines are the synthesis spectra. Vertical lines indicate the location of Ag i and Pd i lines. Offsets of 0.5 were added from the bottom to the top to improve the visualization.
