WinXAS : A New Software Package not only for the Analysis of Energy-Dispersive XAS Data

Abstract
A new software package particularly adapted to the demands o f energy-dispersive X A S (DXAS) and time resolved XAS experiments is introduced. Owing to the dispersive set-up and the employed measuring procedure, treatment of dispersive XAS data requires a series o f additional steps compared to conventional XAS data reduction. WinXAS is running under MSWINDOWS^® and contains some unique features in terms o f a user friendly graphical environment, energy calibration o f dispersive XAS data and the capabilities to process a large number o f consecutive absorption spectra. Since the number o f absorption spectra measured during a single time-resolved experiment can amount to several hundreds, W i n XAS allows to record single data reduction steps and to apply the obtained series on each absorption spectrum of one experiment. Additionally, WinXAS contains a large number o f numerical functions, including conventional XAS data reduction including a complete FEFF [5] interface, smoothing, glitch removal, least-squares refinement, etc.
