1 × (1:10) simulation: velocities of stars belonging to one of the solar vicinity volumes studied in this paper. From left to right: projection of the velocities in the v_z − v_φ, v_r − v_φ and v_r − v_z planes. From top to bottom: all stars, accreted stars and in-situ stars in the selected volume are shown. In all the panels, the black points represents the velocities of all stars in the volume (only 1 particle over 100 is shown), while the orange points indicate those stars in the volume that belong to the Helmi region. Velocities are in units of km s^-1.
