class Faunus::Scatter::StructureFactorPBC< Tformfactor, T, method, TSamplingPolicy >
Calculate scattering intensity using explicit q averaging.
This averages over the thirteen permutations of the Miller index [100], [110], [101] using:
\[ I(\mathbf{q}) = \frac{1}{\sum_i f_i^2} \left < \left ( \sum_i^N f_i \sin(\mathbf{qr}_i) \right )^2 + \left ( \sum_j^N f_j \cos(\mathbf{qr}_j) \right )^2 \right > \]
