FIGURE 3.

The equilibrium singlet distributions, P₁(t_i), from the middle of the β-sheet (solid line) is compared with the distributions from the model of Eq. 3. Here, the triangulation scheme is Tri I. The bending constants, κ_i, are fitted to obtain the best agreement. When κ_i is uniform for all edges (red dashed line), κ = 5 k_BT (the error is ε = 0.094 per bin (pb)). If three different bending constants are used (green dashed line), κ₁ = 8 k_BT, κ₂ = 8 k_BT, and κ₃ = 2 k_BT (ε = 0.055 pb).
