(a) The fitted Qi(Q) function for X-ray total scattering data from crystalline Fe2O3, with the red curve showing the fitted curve, the black curve showing the experimental data after removal of the effective extraneous scattering identified by fitting with low-order Chebyshev functions and the cyan curve showing the extraneous scattering that had been removed. (b) The black curve is the resultant PDF D(r) for Fe2O3 from transform of the fitted Qi(Q) function and taking account of a Gaussian resolution function. The red curve is the result from the lattice simulation described in the text.
