Convergence and uncertainty of atomic polarization charges (e) for salt-bridging amino acid side chain dimers RD and KD. σ and rmsd are, respectively, the average standard deviations of atomic polarization charges and the average root mean squared deviations of atomic polarization charges from those computed with the finest tested grid spacing.
