The radial distribution functions around the Na + and Cl -ions in water, as well as the projected dipole moment of the solvent µ r (Eq. ( )), are shown in Fig. . Similar to the RDF of a central water molecule (Figs. and), the density fluctuations around the ions are short-ranged and largely limited to the FG region. However, the solvent polarization induced by the ions decays over a much longer distance. When the correction potentials are applied, a good agreement of µ r with the FG reference can be reached. The small dents in µ r at R c (2.0, 2.4, or 2.8 nm for the respective systems) are likely artifacts from the group-based cutoff scheme. The same effect is observed for the FG scheme to a smaller extent. It has been shown that the group-based cutoff scheme does not reproduce well the distance-dependent Kirkwood factors for solvents with a high permittivity. The scaling of the dipole moment vector with s 3/2 , as well as the lower degree of statistical averaging in the SG and CG regions, might further amplify the existing artifact.
