Hi Everyone, As Bruce promised, there's a new windows installer for Ifeffit available that includes his latest versions of athena and artemis. There are also some fixes to ifeffit for phase-corrected FTs, and to both ifeffit and Feffit for semi-related bugs in which values from the debye() and eins() functions not always being updated, especially in 'no fit' mode. Ifeffit is now at version 1.0074. The standalone source code for the Feffit program has also been fixed, and is now at version 2.98. Hopefully, we'll get some Mac updates of these fairly soon. Let me know if there are any questions or problems, --Matt
