Normalized mass-to-flux ratio as function of core mass for runs B3M0.4I0 (circles), B3M0.5I60 (triangles), B4M0.4I0 (squares), and B4M0.4I60 (diamonds) at different evolutionary stages. Note that a comparison of equal temporal stages is not possible due to the lack of cores with densities of n ≥ 1000 cm⁻³. For runs B5M…I… no such cores were found! The mass-to-flux ratio is normalized to |$\mu _{\rm c}=0.16/\sqrt{G}$| (Nakano & Nakamura 1978).
