Figure 16.

Undulation spectrum of a bilayer membrane with 4608 lipids sampled in N(Σ = 0)T ensemble for 9.8 × 10⁶τ. The fits of the data to the functional form eq 23 are shown with the upper limit of q chosen as q_max = 0.055 Å⁻¹ (solid line) and q_max = 0.033 Å⁻¹ (dash line). The fitted q⁻⁴-only terms (without protrusion term) are explicitly shown as well (the straight lines in logarithm x- and y-coordinates).
