Hi Everyone, There were several conversations around the XAFS 12 conference on self-absorption corrections for EXAFS. It would be nice to add such corrections (and others, like for deadtime corrections) to Ifeffit. Corwin Booth (at LBL lab, Berkeley) presented a very nice procedure for making these corrections for EXAFS at the conference, improving the work of L. Troger, et al from the mid 1990's. Corwin just sent me the Fortran source code for his program so that it might be included in Ifeffit, and is letting me pass it on. I put the source code (with a Unix Makefile and some instructions) at http://cars.uchicago.edu/ifeffit/contrib/sabcor.tar.gz with a README at http://cars.uchicago.edu/ifeffit/contrib/README.SABCOR I'd be interested in hearing others opinions on this topic, and whether this should be included in Ifeffit. A self-absorption correction that worked better for XANES would be useful too. If you've thought about self-absorption corrections or have some data affected by self-absorption corrections, please check out Corwin's code and let us know what you think of this. Speaking of things to check out, Francois Farges recently created a web page discussingCauchy Wavelet transforms of EXAFS data at http://www.univ-mlv.fr/~farges/wav/ The site includes MATLAB code and references. These transforms are very interesting and I recommend checking out this stuff. There was also a recent email from Harald Funke sent to many people about a different code for Wavelet transforms. If I get permission from Harald, I'll post these codes too. Related to all this, I added a 'Contributions' page to the Ifeffit Web Pages, for "contributions and/or things to consider for XAFS analysis and Ifeffit". Currently, this has links to Corwin's self-absorption correction code, and Francois' Wavelet web page. If anyone has any suggestions for other things to add, let me know. Thanks, --Matt
