The influence of {hkl} (top) on the band profiles and (bottom) on their first derivatives for γ-Fe (master pattern). Plotted as a function of θ − θ{hkl}, all curves are described in degrees but with their first interference order shifted onto the origin. θmax of the first derivative systematically underestimates the Bragg angle. Additionally, the higher the indexed {hkl} the lower the band intensity and band slope. Except for very low indexed {hkl} the band edge widths do not vary.
