[Ifeffit] Proper data processing in Athena with large pre-edge features

Hi everyone, I am working on Vanadium K-edge EXAFS with various VxOx oxides. My question concerns deciding E0 and background spline in Athena. The K edge at 5465eV has a large peak before the edge jump and when subtracting the background and moving to K-space using the default settings, the Bkgd looks incorrect. Any suggestions on how to set the background for further processing? Thank you everyone as this is my firstpost and first EXAFS analysis, -- Christopher J.
