Structural parameters for DODAB monolayer on a subphase containing 10 mM NaCl (obtained from partial structure factors). a0 is the area per DODAB molecule; σA is the width of the lipid (Gaussian) distribution; tA is the slab thickness where tA = σA × (√12/√8); δSA is the solvent separation, i.e. the distance from midpoint of lipid to midpoint of solvent distributions; ζS is the width of the solvent distribution; H is the number of water molecules associated with each lipid as calculated from the number density profiles of the water and lipid. The quoted error is the estimated error.
