Hi Aimee, There is a way to make Athena do this: --Enter -7709 eV in the "E shift" box. --Change the plotting range to be -7800 to -7600 eV (or whatever range you want to use). --Scott Calvin Sarah Lawrence College On Mar 12, 2009, at 12:31 PM, Barton, David (DG) wrote:
Bruce,
I believe what Aimee wants to see is E-Eo (eV) plotted on the x-axis instead of E (eV) in the Athena plot window. I don't think you have the option anywhere in Athena to plot the data like this.
Aimee,
Athena does let you easily export the data as an x-y dataset that can you put into your favorite plotting software and do the simple subtraction that you desire to plot.

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?
