Dear Adam and Mailing List,
I experienced this problem in Athena 0.9.26, only when you import raw data in keV. It seems to me that Athena somehow sets all stepsizes between different points to the largest stepsize you have in your scan – as far as I remember I didn’t have any trouble for scans with only one stepsize. The workaround described by Lucy to convert the raw data into eV (using Excel or any other program) before importing to Athena worked for me as well. Also using an older Athena version (e.g. 0.9.25) worked for me.
The bug has already been discussed in the mailing list last year. Maybe you can find some useful information via the following archive link as well: https://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg06272.html
Best regards,

Dear Adam and Mailing List,
I've checked and found some of my data has a similar problem, I don't know how to solve this using settings in Athena, however as a workaround I have found that if I convert the energy in my raw data file from KeV to Ev before importing it into Athena (using excel) it appears that re-sampling issue does not occur. Hopefully that helps in the short term and gives a clue to what is going wrong with the import.
All the best
