E.s.d.'s and estimated probable error obtained in Rietveld refinements with local correlations 论文

摘要

Estimated standard deviations which are obtained in Rietveld refinements are known to decrease towards zero with the recording step, but serial correlations appear at the same time. A simple calculation which takes into account local correlations has been developed to furnish a reliable estimate of the values they would have if these correlations vanish.
