The systems are: the reference DMPC (D1), four times the area (D2), 7% larger Lz (D3), 51% larger Lz (D4), the reference gA (g1), and twice the area (g2). fw is the water concentration in wt %. The reference system data (D1 and g1) are averages over 16–19 independent trajectories from Table 3. For the larger systems, averages of data from four independent trajectories are shown. SD are indicated in parentheses. Units: Lz in angstroms, fw in weight percent, and G in kilobars.
