Matt and Bruce: First of all, thanks! I just put athena and ifeffit on our beamline computer at MR-CAT for our users to assess data as they take it. It proved to be very easy for the students and newbies to figure out. The question that I have is how does IFEFFIT handle continuous scan data, where the point spacing is almost but not quite uniform in energy all the way through the scan. I have noticed the error of misordered data which can often show up in the continuous scans. We will probably try to fix that ourselves. What is done with the high density data when converting to k-space? Do you rebin (averaging both E and mu data) or do you use a smoothing fit to take advantage of the statistics present in the excess data points, or do you just interpolate and throw away the extra statistics?
