Left: dependance of the difference in los velocity between thin and thick disc stars in the b/p as a function of the difference in radial velocity dispersion at r = r_{b / p} at the start of the simulation. The colour-coding is as a function of the y-axis and is added to help guide the eye in Fig. A.1. The model analysed in this paper is indicated by a black outline. Right: same as left panel, but for the final snapshot of the simulation.
