EXAFIT - A CURVE-FITTING PROGRAM FOR EXAFS

A curve-fitting program for EXAFS has been developed with the aim of providing an efficient data analysis tool for EXAFS. While the fitting algorithm (Marquardt) is standard, the emphasis has been placed on ease of use of the program and high flexibility with parameter input and fitting model. It is possible to fit several spectra simultaneously. This reduces the correlation among the fit parameters in cases where several spectra are fitted with one or more parameters in common. Further features include fitting in k- or R-space, calculation of correlation coefficients, and error determination.
