Structure factor calculation function definition.
In the implementations, this function will do the actual structure factor calculation.
fphidata | Fourier coefficients to be calculated. On output this holds the Fourier coefficients corresponding to the atomic model. | |
atoms | The atom selection from which the density is to be calculated. |
Implements clipper::SFcalc_base< T >.
