My question regards the E0 of the data and standard scans. Even though the scan itself shifted, the E0 still remains where it was when I imported it, prior to aligning the reference channels. The peak itself shifted, but the program still marks the E0 at the previous peak position. Is this an issue?

That behavior is by design. It's not obvious to me that shifting the E0 value by the same amount as the alignment energy shift is the correct thing to do in any given situation. Not doing so seems like it will cause the least surprise.

If so, how do I adjust the E0 of the scans the same amount that the reference channels shifted?

It does say how much the scan shifted, so I went in and manually changed the E0 of each scan so that it correlated with this shift. Would this be an effective solution? If this does solve my problem, is there a less labor-intensive way to solve it in the program?

You can never go wrong by the manual approach, but it is tedius. Happily, there are many labor-saving features in Athena. Here's some reading from the manual: Constraining parameters: http://bruceravel.github.io/demeter/aug/params/constrain.html Energy menu, which has options for operating on all groups or on the marked groups: http://bruceravel.github.io/demeter/aug/params/e0.html Processing your data as it is imported: http://bruceravel.github.io/demeter/aug/import/preproc.html While there are certainly other things that Athena /could/ do in this area, I have found that being adept at the features described on those manual pages takes most of the tedium out of the sort of chore you are asking about.
