(Above) Fluorescence counts in the centre and right crystal analysers, NFF. (Below) A comparison of `consistent' and `inconsistent' standard deviation (variance) measures of σsd versus Eem, for the centre and right crystal analysers after scaling in the tail region of the Kα1 spectrum. The `inconsistent' calculation oscillates around the `consistent' estimate and indicates that the consistent method is a good upper bound for the uncertainty of the weighted mean.
