Half-mass radius compared with DM-halo scale length (Plummer radius) for each fractal radius. The circular dots represent the initial collapse scenario, while the square ones describe the behavior of the half-mass radius in the equilibrium scenario. The UMa II 3D half-light radius is represented by the dotted yellow line. Due to the variety of fractal radii, a color gradient is used to represent it. Error bars are omitted.
