Average (dash-dotted violet lines, labelled ‘avg-μ_sc’) and most probable (violet squares, labelled ‘MP-μ_sc’) values of the cluster proton number Z (top panel) and mass number A (lower panel) in the self-consistent MCP calculations as a function of the total baryon density n_B at k_BT = 1 MeV. For comparison, the OCP solutions (black solid lines), as well as the average (orange dashed lines labelled ‘avg-μ_OCP’) and most probable (orange dots labelled ‘MP-μ_OCP’) values in the perturbative MCP are also plotted.
