^aEach sample contains two lipid bilayers, each consisting of 680 POPC molecules arranged on two leaflets. The δV parameter measures the standard deviation in the volume of each bilayer averaged over time, and it is closely related to the bilayer volume compressibility (see text). The error bar is implicitly given by the number of digits.
