Dependence of prolaticity distribution on cosmology and $\log {\sigma }_{NL}^{-1}$. We define four bins of $\log {\sigma }_{NL}^{-1}$ and then compute the cumulative distribution function of prolaticity, in each bin. The curves correspond to three cosmological models superposes, not only for F = 0.5 (median prolaticity) but all along the distribution (between the first and ninth decile). Hence, one can say that the whole prolaticity distribution is related to the nonlinear fluctuations in a non-cosmology-dependent way.
