Normalized structure factors. III. Estimation of errors

A method for calculating the expected errors in |E_h| values is outlined. It is based on the precision of the measured data and the Wilson-plot parameters: and allows for errors arising from the use of the profile scaling function and/or the index rescaling procedure in the normalization scheme. Six refined structures are used to test the estimated errors in |E_h| against values deduced from a comparison with the 'true' normalized structure factor |_h|.
