Development of the radius of the bound cluster mass over time for the case of 30% and 70% SFE. The solid lines give the results for clusters with pc and 70% SFE (model CK 1) representative for compact clusters, and the dashed lines indicate clusters with pc (model LK 1) and 30% SFE depicting loose clusters. The black lines indicate the half-mass radii and the red lines the 10% Lagrange radii. The red dotted line indicates the 5% Lagrange radius for the loose clusters. For the compact clusters the 5% Lagrange radius would be basically indistinguishable from the 10% Lagrange line in the representation chosen here.
