[Ifeffit] Sorry

[Richard Mayes]

Chris,

In cases where intense pre-edge features are observed, such as the one you
attached, you should manually set the Eo and not accept the Athena
defaults.  I usually start with half-way up the absorption edge (you can
look at the derivative and move the Eo value to the maximum in the
derivative; however, make sure you don't move it back to the pre-edge).

More detailed information on setting Eo and background removal can be found
here:

Also, www.xafs.org is an excellent resource for more information.
