Editing EXAFS (section)

==Post-processing== 

These steps should be followed in Athena, from your Virtual machine. 

* Open Athena. 
* Import chi.dat. 
* Select chi(k) as data type.  
* Click in "replot".  
* Select the element and edge. (i.e., Pd, K-edge).   
* Edit k-range [3.0;14.0], dK=1. 
* Select plotting k-weights: 3. 
* Apply a forward Fourier transform. 
* Change plot to R-space, Magnitude-Magnitude. Select and unselect "real part" to update the graph. This will generate a plot |chi(R)| in Å^(-4) as a function of the radial distance in Å. 
* To change the units of chi(R), change the k-weights.  
* In the main window, clic on file > save current group as > chi(R). 
* Save the file as .dat inside your Windows virtual machine. Then move to the shared folder to do the analysis.
* You can now do a fancy plot in Origin, showing the chi(R) data you got from Athena.
