    • The image density profile is calculated in the mean-field approximation for a flat interface as ρ (z) - ρc ± [ρ (±) - ρc] tanh (-z/2ξ) with the assumption that ρ (-) represents the density in the center of the droplet. The actual profile is smoothed even further by fluctuations. Moreover, the density profile for a suspended droplet, as obtained numerically by JCPSA6 0021-9606 10.1063/1.1730447
