SASfit

SASfit is a simple, handy, and very easy to use application specially designed to offer you a program for fitting structural models to small angle scattering data. It can calculate integral structural parameters like radius of gyration, scattering invariant, and Porod constant. It can fit size distributions together with several form factors including different structure factors. Additionally an algorithm has been implemented, which allows to simultaneously fit several scattering curves with a common set of parameters. The global fit helps to determine fit parameters unambiguously which by analyzing a single curve would be otherwise strongly correlated.
