[Ifeffit] Normalization in Athena

Hey everybody,
while I try to figure what effect normalization has on Linear
combination fitting in my lead L3 edge XANES system, I came accross
this problem:
Athena does not normalize correctly:
Normalization in Athena (post-edge): using 1.order normalization, no
flattening (which in this case is irrelevant anyway), points +199 eV
and +200 eV above E0.
Normalization in Origin (post-edge): using point 13235 eV (+200 eV
above E0); dividing the spectrum column by that value.
See the two examples in the attachment.
In both examples the normalized spectrum imported from Athena does not
have the norm value of 1 at 13235 eV. Why is that? The offset is also
not the same for every spectrum. That undoes the normalization
routine.
Greetings,
Lisa
