Heliocentric distance against Galactic latitude for different snapshots of the simulations by Laporte et al. (2018). On the left is the H2 simulation, and on the right is the L2. In both cases, the Sun has been placed at (x = −8 kpc, y = 0 kpc). The stars shown in each panel correspond to those in slices of Galactic longitude 120° <  l <  240°. The snapshot at 4.3 Gyr for H2 corresponds to the one where ACS- and MNC-like structures (top and bottom feathers, respectively) were reported in Laporte et al. (2019b).
