Hi, I wonder if you can help: I'm using Athena to process some XANES data and wish to export the derivative data so that I can use a package such as Excel to prepare the data for publication. However, the derivative data that is presented visually in the graphics window is a much cleaner, smoother data set than the one I get when I export it in either deriv Mu(E) or deriv Norm(E). I tried the smoothing option in Data-Smooth mu(E) with 3 iterations and again with 10 iterations on the interpolative smoothing. Both gave far noisier data than the data shown in the Graphics window. Please can you tell me how to get exported derivative data that will be (more or less) the same as that shown in the graphics window? Basically I' hoping for WYSIWYG if that's possible? Any thoughts or suggestions would be very welcome and thanks for your time. -- Dr. Paul Bingham Postdoctoral Research Associate Immobilisation Science Laboratory Dept. of Engineering Materials University of Sheffield Mappin Street Sheffield S1 3JD UK Email: p.a.bingham@sheffield.ac.uk Direct Line: (0114) 2225473
