This already happens in Athena. It was requested back in 2014:
https://www.mail-archive.com/ifeffit@millenia.cars.aps.anl.gov/msg04747.html
and Bruce did include energy as a column in the exported chi file in a
future release
(present in 0.9.26)...e.g.
# XDI/1.0 Athena/0.9.26
# Element.edge: K
# Element.symbol: Fe
# Column.1: k inverse Angstrom
# Column.2: chi
# Column.3: chik
# Column.4: chik2
# Column.5: chik3
# Column.6: window
# Column.7: energy
-R.

Dear mailing list,
Is there any way to save data as Chi( E),i.e., energy one column
and chi(E) in the 2^nd column? This was possible in the past and
it would be great to have that to be able to import into excurv.
Sure:
~> larch
larch> dat = read_ascii(datafile_name)
larch> # ... make sure you have mu(E) as 'dat.energy' and 'dat.mu
<http://dat.mu>'
larch> autobk(dat, rbkg=1.0, kweight=1) # may want other options
larch> write_ascii('my_chie.txt', dat.energy, dat.chie)
larch> plot(dat.energy, dat.chie, xlabel='E (eV)', ylabel=r'$\chi(E)$')
Hope that helps,
--Matt
