As it can be inferred from the data shown in Tables II, III, and IV, the computed errors ση do not seem to show a significant variation with the system size. This is observed, although the accuracy of the computed self-diffusion coefficients is decreasing with decreasing system size. Apparently, the increasing difference between D 0 and D PBC,zz with decreasing system size is almost exactly compensating for this loss of accuracy. This means, that the exponent β, characterizing the system size-scaling of the computed error of the viscosity is accordingly represented by a scaling exponent of β ≈ 0.
