Comparison of the configurational entropy of the membrane calculated using the Fourier method with (S1) and without (S2) consideration of the induced curvature field at A_ex = 6%. S3 in the figure, is defined without any fitted parameters by directly relating the height–height undulation spectrum to the frequency. In this study, three replicates for each model system were included in the entropy estimates. Error bars, (horizontal parallel lines inside the symbols), are smaller than the size of the symbols.
