Cluster models for estimating fly-by probabilities.

Model name Resembling mcl (M) rh (pc) (M) Nsolar Reference
C1 ONC 2000 0.8 0.7 60 [1]
C2 Arches 50000 0.2 1.6 3300 [2]

Notes. Here, mcl is the total cluster mass and rh is the half-mass radius. The mean stellar mass,, and the approximate number of solar mass stars, Nsolar, were calculated based on the mass functions for the respective cluster. Model C2 resembles the “initial” Arches, not the contemporary Arches.
