It was allowed in earlier versions. The fractal S(Q) in this model ''also'' includes the radius parameter (as well as the spherical P(Q)). So there are two questions: 1. Did 3.1.2 and earlier versions only apply polydispersity to P(Q), or to P(Q) ''and'' S(Q)? 2. Should polydispersity be put back into this model for 4.2?
