Single layer versus bilayer density profiles. Average of A80 layer profiles about their centers (dotted black), A80 average profile shifted to center on bilayer positions (solid black), summed shifted profiles (dashed blue), and plane-averaged A4 profile (solid red). Data were plane-averaged, collapsed to [001], and normalised such that charge density integrated to one.
