[Ifeffit] E0 in Co3O4

Dear list,

I enclose an Athena project with a XAFS spectrum of Co3O4 with a metallic
Co reference.
Athena by default has chosen E0 at the absolute maximun of the derivative
curve (at 7727.8eV) which in my opinion is too high because it is at the
white line zone.

I believe that E0 should be the previous maximun in the derivative at
around 7722eV, which would be at the rising edge.

Am I wrong?

I would appreciate some help with the criterion to determine the right
