EXAFSPAK is a suite of XAS data analysis programs developed by Dr. G. N. George of SSRL. Features include a degree of automation, an efficient curve-fitting algorithm using analytically calculated derivatives (allowing more rapid convergence to the best-fit than with numerically calculated ones). Other features include the ability to link different variables together in the curve-fitting process, and the availability of search routines and best-integer fitting functionality. The curve-fitter can utilize the ab initio multiple scattering code FEFF.
