FSTW-YIFZAP. Left: Normal probability plot for the main refinement. There is a distinct step near the origin together with some outliers at the extremes. Right: Normal probability plot for the post-refinement analysis of the Friedel differences. The central region has a unit gradient, but the very large deviations in both tails lead to a meaningless best straight line. Either the observed Friedel differences or the weights computed from their standard uncertainties may be in error. |
