Intrinsic ellipticity ϵ as a function of M/M_* for initially cold spherical systems in live (circles) and frozen (squares) halos (left panel); and for initially cold clumpy systems in live (downward triangles) and frozen (upward triangles) halos (right panel). The empty and filled symbols refer to ϵ evaluated inside r_70% and r_90%, respectively. The simulation parameters are summarised in rows (14–17) of Table 1.
