Figure 11
(Left) Reciprocal-space data from NPDF Si standard measurement, separated by bank (bank 1 is red, bank 2 is cyan, bank 3 is orange, bank 4 is purple). In all banks, the binning employed is $[\Delta Q = 0.01]$ Å⁻¹. (Center) Two example peaks are highlighted at Q = 3.27 and 8.26 Å⁻¹, demonstrating the emergence of a miscalibration effect at higher Q values. (Right) The results of fitting the positions of the 18 largest intensity peaks in the individual banks, relative to expected positions, plotted as a function of their offset in Q.
