Evolution of the Lagrangian radii r5% enclosing 5% of the system’s mass (top panels) and central velocity dispersion σc evaluated for particles inside r5% (bottom panels) for models with a Salpeter mass function (left) and equal masses (right), and α = 10−4, 3 × 10−4, 10−3, 3 × 10−3, and 10−2. In all cases the systems were initially isotropic and N = 105 so that μ = α × 105.
