Fig. 9.

Galactocentric radial velocity vs. galactic longitude. The black line shows the linear fit of the full GALCEN sample, while the red line shows the fit for metal-rich stars [Fe/H] > 0, and the blue line shows MP stars. The shaded area shows the 95% level of confidence interval. The green points are stars inside 0.4 degrees of galactic latitude. See text for details.
