Notes.Run (Col. 1): identifying name of the run; NA (Col. 2): number of particles in the first cluster (identified with pop. A); MA (Col. 3): initial mass of the first cluster; rA (Col. 4): scale radius of the first cluster; QA (Col. 5): virial ratio of pop. A; NB (Col. 6): number of particles in the second cluster (identified with pop. B); MB (Col. 7): initial mass of the second cluster; rB (Col. 8): scale radius of the second cluster; QB (Col. 9): virial ratio of pop. B; Δv (Col. 10): initial velocity shift between the centres of mass of the two clusters; D (Col. 11): initial distance between the centres of mass of the two clusters; m1,m2 (Col. 12): initial mass of the members of the most massive binary system in each run. The 21 runs listed in this table are a selected sample among all the runs we performed. They represent the runs that best match the observations (runs 1, 2, 13 and 21), and/or that are important to understand the influence of various parameters on the results.
