Distribution in the L_⊥ − L_z space of stars in some solar vicinity volumes, for the 1 × (1:10) simulation (first and second rows), for the 2 × (1:10) simulation (third and fourth rows) and for the 4 × (1:10) simulation (last two rows). From left to right: distribution, in the selected volume, of all stars, in-situ stars and accreted stars, respectively. Rightmost column: only the distribution of accreted stars is shown (gray-scale), with the contours representing the accreted population (thick lines) and the in-situ one (thin lines), respectively. The two rectangular areas correspond to the Helmi region and to the extreme prograde region (see text for details).
