Compiled and tested with Turbo C++

This package was developed to reduce EXAFS (Extended X-ray Absorption Find Structure) data, initially on Turbo C/C++, so DOS-like GUI was provided.

It includes two parts:

The fist part commits the pre-edge subtraction, edge normalization, post-edge fitting, E-to-k conversion, k-space weighting, windowing, fast Fourier Transform, and inverse Fourier Transform for amplitude and phase function extraction. Files used: "wan.h", "XAFS.cpp", "PLOTX.cpp", "preedg.cpp", "postedg.cpp", "FFT.cpp", "IMEX.cpp"

The second part is designed to extract local coordiation parameters of X-ray absorbing atom (including coordination number, coordination distance, disorders, energy shift) from curve fitting based on simulated annealling approach. Files used: "XFIT.H", "FITXK2.CPP", "amebsa1.cpp", "spline1.cpp", "plot.cpp", "IO.cpp".
