Figure 1
Real-space (panels 1 and 4) and reciprocal-space (panels 2 and 3) functions showing consecutive steps 1, 2, 3 and 4 to calculate the real-space PDF as a back-Fourier transform of scattering factor F(Q) indicated by solid black arrows. The histogram-based method is shown by the black dashed arrow (directly from step 1 to 4). |
