We also provide the shear viscosity values of the membranes obtained from the ts of Eq. ( ) in Fig. To streamline the selection of force elds that best capture the eect of CHOL on dierent membrane properties, we dened quantitative quality measures for simulations. For this we calculated for all the force elds their relative deviations from experiments (dierence between simulated and experimental values divided by the experimental value) using interpolated data for the form factor minima, the order parameters of the two acyl chains, and the diusion coecients. The quality evaluations are shown in Fig. .
