Table 3. Fitted NR parameters for different lipid compositions at 40 mN m−1. σ is roughness, V is molecular volume and d is thickness of the indicated slab, nw is the number of water molecules per lipid and AM is the molecular area. The CL-containing monolayer values are given per pair of chains to facilitate comparison. The numbers in brackets represent 95% confidence ranges from the fits.
