XAS DATA ANALYSIS SOFTWARE DEVELOPMENT

现有的EXAFSPAK XAS数据分析程序套件已经 年内全面升级，Open VMS(VAX和 Alpha)和Unix版本可供用户下载到其 来自SSRL WWW站点的家庭计算机系统实验室 (http://www-ssrl.slac.stanford.edu/exafspak.html).的发展。 下一代分析代码即将完成，并且 预计将于1999年向用户发布。所有的数值例程都有 进行了广泛的返工，并与 图形用户界面部分的代码，以便于 未来的可扩展性和高度的可移植性。图形用户 接口已使用矢量化地址表法重写， 它允许依赖于操作系统的代码部分 分开。新程序在Open-VMS和Unix操作系统下运行 具有单一源集的系统，并包括图形 与从头算理论包FEFF的接口。

The existing EXAFSPAK suite of XAS data analysis programs has been extensively upgraded during the year, and both Open VMS (VAX and Alpha) and UNIX versions are available for users to download to their home computer systems laboratories from SSRL's WWW site (http://www-ssrl.slac.stanford.edu/exafspak.html). The development of the next generation analysis code is nearing completion, and is expected to be released to users in 1999. All numerical routines have been extensively re-worked and completely separated from the graphical-user-interface parts of the code, to allow for ease of future expansion and a high degree of portability. The graphical user interface has been rewritten using a vectored address-table approach, which allows operating system dependent parts of the code to be separate. The new programs run under Open-VMS and UNIX operating systems with a single set of sources, and include a graphical interface to the ab initio theory package FEFF.
