Final values of f₊(f_p), f_E, ι₈₀ and λ for the spherical initial conditions as a function of α, for N = 10⁴. The points are the average values for N_s = 20 realisations for each α ≠ 0 and for 47 realisations in the case α = 0; the indicated error bar is the corresponding standard deviation σ (for λ we show the error on the mean ). The lower panel also shows (red dashed points) the angular momentum of the bound mass normalised to L₀. For the smallest values of α, the angular momentum generated actually decreases but, because of the increasing mass (and energy) ejection, the characteristic angular momentum of the final bound mass decreases even faster.
