Hi All,

  I have a rather simple question and a reply for either Larch or athena would be welcome.  I have calculated a number of structures using DFT and have run feff on each of the appropriate sites and have then averaged the E(k) results.  I have no problem reading in the data to athena, however, due to the lack of a pre-edge baseline, it is typically not possible to choose a reasonable “pre-edge” baseline so that I can plot the data for the different structures in “flattened” mode. The “post-edge” baseline works very well with the default values (as there is literally no noise in the spectra).  My question is how can I induce athena to plot the E(k) data for the different structures in “flattened” mode. Ultimately, I will end up taking a Fourier transform into real space so I would also like to have a proper baseline so I can compare intensities as well.  In effect, the data from feff9 is already normalized.  Thanks for any suggestions!
