The values represent averages and standard deviations that were calculated based on four different simulations. The position of the smeared surface charge was zGC = 20 Å and η = 1.0.
The total free energy.
The conformation free energy.
The solvation free energy.
The Coulombic free energy.
The average value of the z-coordinate of the centroid of the chain; the membrane midplane was at z = 0.
As measured by Persson et al. (33).
