Fig. 4


Galactic rotation velocity derived for the particles in the simulations for the thin (red) and thick disk (black). The particle’s velocities are treated similarly as the observed stars described in Sect. 3, and only one in ten particles are shown in the figure. The linear fittings give dV/d[Fe/H] = −16.9 ± 0.2 km s-1 (thin disk) and dV/d[Fe/H] = + 16 ± 1 km s-1 (thick disk).
