We can compare the rmsd achieved with this 10 9 100 grid (0.00672) with a fit under otherwise identical conditions but different grids: a coarser 10 9 50 grid leads to an rmsd of 0.00678, which is barely statistically worse (on a one standard deviation confidence level), and a finer grid with 20 9 200 grid leads to an rmsd of 0.00670, which is statistically indistinguishable. Thus, a 10 9 100 grid is of sufficiently high resolution to extract the entire information content of the experimental data.
