). This is due to spectrometers reporting energy based on several foils and unit-cell determinations being made based on multiple reflections.
1The selection of 1% error and 10000 photons has been made arbitrarily and is for comparison purposes. It should be noted that errors in unit-cell dimensions do not scale exactly with the percent error in single foil energy measurements (Hanley et al., 1997). This is due to spectrometers reporting energy based on several foils and unit-cell determinations being made based on multiple reflections.
