Figure 2
The total (volume) (a) and cross-section (b) PDD functions as a result of the IFT procedure for scattering from amyloid fibrils in 100% D₂O. The functions are calibrated to unity. In (a) the arrow indicates a characteristic cross-section radius of the effective homogeneous cylinder. In (b) the arrows indicate characteristic pair distances in the average cross section of the effective elongated cylinder.
