The diagram shows r_eff as a function of mass of the observed ECs and UCDs (circles) and the modeled merger objects (stars), combining Figs. 1 and 9. Two additional models with calculated on a circular orbit at 60 kpc (M^CC = 10^5.5 and 10^8.0 M_⊙) are plotted as grey stars. The dotted lines connect the additional models on a circular orbit with the corresponding models on an eccentric orbit.
