Fits (black lines) to GIXOS data (symbols) of (a) DPPC and (b) POPC monolayers at various surface pressures (offset by 500 and colour-coded), and the corresponding SLD profiles to the fits. The SLD profiles from different pressures are offset by 2 and colour-coded the same as the GIXOS data. Above the SLD profile is the volume occupation fvol of the tail compartment as a dotted line, the headgroup compartment as a dot–dashed line, the sum of the two compartments as a solid line and the bulk water as a dashed line. They are offset by 100% and colour-coded. |
