The ion-solvent electrostatic interaction energies U ele and their Coulomb-corrected counterparts FIG. : Ion-solvent electrostatic interaction energies evaluated for Na + and Cl -with different scaling factors and biasing schemes: "FG" is the FG system in the large box (L = 8 nm) with cutoff R c = 1.2 or 1.4 nm, "FG/S" is the same FG system in the small box (L = 3 nm), "CG" is the AdSoS system with s max = 2.0 and cutoffs R c = 2.0, 2.4 or 2.8 nm without correction potentials, "CG+B" is the same CG system with the correction potentials. (Top): Raw energies from the Coulomb reaction-field scheme in Eq. ( ). (Bottom): Corrected energies according to Eq. ( ).
