I have collected full XANES and EXAFS spectra. I have imported the full spectrum into Athena. I am now trying to analyze using XANES, but I am have trouble figuring out how to set an absolute energy, i.e. 7709 eV = 0 eV or such, and have the energy scaled negatively and positively. It is probably super simple, can anyone please help?
Hi Aimee, Data calibration is explained in the Athena User's Guide: http://cars9.uchicago.edu/~ravel/software/doc/Athena/html/process/cal.html If that is too terse or does not address your question, you might consider making a small Athena project file which demonstrates what you are confused about and then post that to the mailing list. Posting data is usually the best way to get a concrete answer.
