Notes. From left to right, the meaning of the columns is as follows: model name, initial stellar mass of the cluster Mcl(t = 0), initial mass Mgas(t = 0) of the gas component, initial half-mass radius rh(0), gas expulsion timescale τM, half-mass crossing time th, relaxation timescale trlx, and timescale for mass segregation for 10 M⊙ stars tms. The last two columns give the median escape speed of stars in tails I and II (
and 
), respectively. The difference in the timescales for clusters with the same stellar mass and radius (e.g. for models C03G13 and C03W02) stems from different velocity dispersion due to the gaseous potential. The models performed for only one simulation are in italics.
