FIG. 6.

Measured FWHM of selected peaks from the diffraction data shown in Fig. 5: (a) as measured (symbol) and fit (line) to the IRF, as discussed in section IVc; (b) as a Williamson–Hall plot; (c) expressed in wavelength-independent units as .

FIG. 7.

Rietveld refinement using a high-resolution diffraction pattern from a mixture of two NIST SRM materials [ Si (640c) and (676)]. Crosses indicate averaged data from the combination of the 12 detectors, the red solid line shows the computed results, while the green line shows the fitted background. The blue line at the bottom shows the difference between the observed and computed results.
