I_0 = (bp - (k * Rg^2) * eta_s)^2 with k = 1 nm. k * Rg^2 = volume approximation

formfactor(dataset)

Calculates the Rayleigh function of this model. Reimplement this for new models.

parameters = (None, None, None, None)

shortName = 'Gaussian Chain'

volume()

Calculates the volume of this model, taking compensationExponent into account from input or preset parameters. Reimplement this for new models.
