Notes. The table lists N-body simulations modeling both the coalescence of multiple subclusters and the evolution of individual clusters under different gas-expulsion modes. More details are provided in Sect. 2 and Appendix A. “Time” denotes the point at which the simulation is terminated; the cluster may or may not have dissolved by this time.
