6kw6Scalo3 | 6122 | 11 | 5.6 | 1.0 | 0.18 ± 0.05 |

Notes. The first column shows the name of the model that describes the basic features of the model. The first numbers together with k indicate the number of stars in the model. The number following w is the W0 parameter of the initial King density distribution. The next set of letters is the name of the initial mass function (IMF) and the last number is the power of 10 of the upper-to-lower-mass-ratio of the IMF. For instance 6kw6Scalo3 is the code name of a system of 6k = 6 × 1024 = 6122 stars distributed according to a King density profile with parameter W0 = 6 and masses given by a Scalo IMF with mupper/mlower = 103. For all models presented here, the upper mass limit is 100 M⊙ and the lower mass limit is 0.1 M⊙. The second column shows the number of stars in the simulation. The third indicates the number of runs for the model. The fourth column gives the average half mass relaxation time in Myr. The fifth column shows the average core collapse time in Myr calculated using Myriad. In the sixth column, the calculated core collapse time in units of trlx is presented.
