Ratios of the i-th eigenvalue λ_i of the energy shear U_įj to the i-th eigenvalue $a_{i}^{2}$ of the inertia tensor I_ij, each normalised by their respective trace: $ρ_{i} \equiv (λ_{i} / ϵ) / (a_{i}^{2} / I)$ ${\rho _i} \equiv \left( {{\lambda _i}/} \right)/\left( {a_i^2/I} \right)$ . Equation (12) would predict this ratio to be 1, whereas on average ρ₁ > 1 and ρ₃ < 1, meaning that protohaloes are slightly less elongated than what suggested by this simplest prediction.
