Hi,
find attached an example with the "flatten-problem". thanks a lot,

"Hi,
I have a normalization problem with Athena. If I turn on the "flatten" option in the background removal section, Athena creates in some of
Hi Jens, I believe the problem is related to the structure in the data before E0. If you choose e0 to be at the beginning of the structure then the normalization is handled better by Athena. Take a look at the attached project file. The first data set with e0 on the edge as you would choose for EXAFS analysis (e1) shows the error that Jens reported. The second data set with a lower value for e0 at the beginning of the structure (e2) gets the job done.
