Masses of multiple star systems in the SC (left), T1 (centre), and T2 (right) of the main model (top) and the five M2 models (bottom) as seen by an observer over the real total mass of the systems at the end of the simulation (T = 300 Myr). Binaries composed of only main-sequence stars are shown as dots, while multiple systems containing non-main-sequence stars are displayed as crosses. The colour denotes the mass ratio of the system.
