Relative water density η as a function of distance from the protein surface, d, expressed as percentage deviation from average bulk water density η(d) = 〈ρ(d)〉/〈ρ(∞)〉 − 1. Error bars denote the statistical error caused by dynamical fluctuations in the simulation. The surface, defined as a boundary of the protein, is separated on average by ≈1.3 Å from the protein surface atoms.
