From left to right: distribution in the L_⊥ − L_z space of halo stars in a 10 kpc volume around the Sun, for the 1 × (1:10) merger (left column), for the 2 × (1:10) merger (middle column) and for the 4 × (1:10) merger (right column). The first, second and third rows show, respectively, all stars in the selected volume, in-situ stars only and accreted stars, only. Colors code the stellar density, as indicated in the color bar. The fourth and last rows show, respectively, the fractional contribution of in-situ stars and accreted stars, to the total. As in Fig. C.8, in all panels, to minimize the contribution of disc stars, only stars at vertical distances z from the disc plane greater than 3 kpc have been selected.
