Left panel: U component of velocity as a function of [α/Fe] for the stars in the sample (open red circles represent stars on the thin disk sequence; solid red circles represent stars on the thick disk sequence). The two thin and thick curves are running dispersions for U component of the velocity of the thin and thick disk sequence stars, calculated as a function of [α/Fe] (over 50 stars). Right panel: U component of velocity as a function of age. Open blue circles represent thin disk stars and solid blue circles represent thick disk stars as defined in Fig. 5.
