Hi folks, This morning I posted a new version of the source code package and a new windows executable for Athena on my web site. The changes in Athena include: 1. The ability to read a data file from a multi-element detector and have each channel be made into a separate group. This allows you to examine and discard individual channels before making a summation. 2. Added a simple log-ratio/phase-difference analysis. This can be accessed from the "Analysis" menu. It is currently undocumented, but if you already know how log-ratio works, it should be fairly clear what is going on. 3. Fixed (I think!) a bug in which reading in data and selecting the raw detector data type would crash the program on Windows. 4. Fixed a bug that made it impossible to save chi(q) data correctly. There are some outstanding problems with both the multi-element thing and the log-ratio thing. The most serious of these is one that effects a multi-element file with very many columns. It is quite possible for most of the columns not to be displayed in the column selection dialog. This will be fixed next time. I want to thank Dale Brewe and Oded Kleifeld for their useful bug reports. I also want to thank all of the participants and instructors of the recent EXAFS course at NSLS for putting Athena and Artemis through their paces. Several issues, mostly with Artemis, surfaced at the course and will get my serious attention this fall. *** For those of you receiving this who are not subscribed to the ifeffit mailing list, please consider subscribing.

Please note that the installer has NOT been updated to include it. *** For those of you having strange problems on Windows 98, there are some links on my downloads page that may help you deal with certain inherent limitations of that charming operating system.
