Detailed Description

class that deals with form factor computation two form factors are supported: (i) zero form factors for faster approximated calculations (ii) full form factors for slower accurate calculations

Each form factor can be divided into two parts: vacuum and dummy. dummy is an approximated excluded volume (solvent) form factor. The approximation is done using Fraser, MacRae and Suzuki (1978) model.
