In the absence of a biasing potential (Fig. ), the effect of the FG-SG and SG-CG interface on the orientation of the water molecules has a longer range compared to its effect on the density, with the polarization in the FG and CG regions being highly affected. The magnitude of polarization artifacts increases with s max (i.e. with the s-gradient in the SG region), and decreases upon increasing the cutoff R c . This effect is largely independent from the density artifacts. Applying a correction potential for the density alone does not affect the polarization in a significant manner (data not shown). Figure
