This already happens in Athena. It was requested back in 2014:
and Bruce did include energy as a column in the exported chi file in a future 
(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

Dear mailing list,
Is there any way to save data as Chi( E),i.e., energy one column and chi(E) in 
the 2nd column? This was possible in the past and it would be great to have 
that to be able to import into excurv.

   larch> dat = read_ascii(datafile_name)
   larch> # ... make sure you have mu(E) as  '' and 

   larch> autobk(dat, rbkg=1.0, kweight=1)  # may want other options

   larch> write_ascii('my_chie.txt',, dat.chie)
   larch> plot(, dat.chie, xlabel='E (eV)', ylabel=r'$\chi(E)$')

Hope that helps,
