REX2000 Version 2.5: Improved DATA Handling and Enhanced User-Interface

摘要

XAFS analysis can be applied to various fields such as material science, environmental study, biological science, etc. and is widely used for characterization in those fields. In the early days that XAFS technique was started to be used, scientists wrote their own code for XAFS data analysis. As XAFS technique became very popular and XAFS community grew big, a several analysis code or package had been developed and submitted for people to use. The REX2000 is one of those XAFS analysis packages, which is commercially available. Counting up from its predecessor “REX”, REX2000 has been used for more than 15 years in XAFS society. From the previous modification in 2003, a major change was made in this year of 2006. For a dynamical study of advanced material, many XAFS DATA were measured (quick XAFS and in-situ XAFS) and hundreds of DATA sets need to be processed. The REX2000's DATA handling is improved to cope with those huge volume DATA at once and report the fitting result as CSV file. Well-established user-interface is enhanced so that user can customize initial values for data analysis and specify the options through graphical interface. Many small changes are made and described in this paper.
