Sas-temper: Software for fitting small-angle scattering data that provides automated reproducibility characterization

Abstract

The analysis of small-angle X-ray and neutron scattering data is both time-consuming and fraught with the challenges intrinsic to non-linear least squares minimization processes. These difficulties are compounded by the relatively limited information content of the data. The software sas-temper addresses the first two issues by automating the process of repeated, independent fits to a single data set and by automatically analyzing the set of results generated. The output of sas-temper enables the user to easily decide if additional data fitting is required. The plots and the analysis of the set of results also simplify refinement of the parameter search space.
