Comparison of the radial profiles of collapse simulations at a central density of ρ_c = 6 × 10^-2  g   cm^-3 using various initial parameters (see Table 2 for details). The different panels display the following as a function of radius: (a) and (g) density, (b) and (h) gas temperature, (c) and (i) entropy, (d) and (j) radiative luminosity, and (e) and (k) enclosed mass. Panels (f) and (l) display the thermal evolution at the centre of the grid. Panels (e) and (k) show the colour legend.
