Hi, I just posted a new release of the athena source code. I have not yet made a new windows binary. This version is 2002.03.08. New in this release: ** Phase corrected Fourier transforms (requires ifeffit 1.0069 or later) which make use of tables of central atoms phase shifts as I discussed on the feffdevel list http://cars9.uchicago.edu/feff/feffdevel/msg00082.html ** Spline clamps, both high and low, but with discrete, menu-chosen scaling factors. This is not yet documented, but the basic idea is that you can put restraints at the high and low end of the spline range in the autobk algorithm to coerce the spline to go through the data at those points. Try autobk with the high clamp set to Strong -- very cool! ** a few bug fixes -- as always ;-) Kind of a small list, but PCFTs and spline clamps are both fairly major bits of user functionality, so it seemed worth making a new release. As always, point your browser at http://feff.phys.washington.edu/~ravel/software/exafs/ for the latest. B P.S. Those of you to whom I sent this message by blind carbon copy should go to http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit and subscribe to Matt's great, new ifeffit mailing list. In the future all announcements will be made there. -- Bruce Ravel ----------------------------------- ravel@phys.washington.edu U.S. Naval Research Laboratory, Code 6134 phone: (1) 202 767 5947 Washington DC 20375, USA fax: (1) 202 767 1697 NRL Synchrotron Radiation Consortium (NRL-SRC) Beamlines X11a, X11b, X23b, X24c, U4b National Synchrotron Light Source Brookhaven National Laboratory, Upton, NY 11973 My homepage: http://feff.phys.washington.edu/~ravel EXAFS software: http://feff.phys.washington.edu/~ravel/software/exafs/
