Population B. $S_m^f/S_m^s$ as a function of $S_s^f/S_s^s$ (top left panel) with a zoom-in of the region in which the two ratios are equal or very close to unity (top right panel) and ∆_CoM as a function of $S_s^f/S_s^s$ (bottom left panel) with a zoom-in of the region in which $S_s^f/S_s^s$ is equal or very close to unity and ∆_CoM is equal or very close to zero (bottom right panel). Disrupted systems are not displayed in this figure because it was not possible to compute their NAMD and ∆_CoM.
