Dear Bruce and dear all,
I have the same problem with data import in Athena 0.9.26 that Andreas
has just described and that, if I am not mistaken has already been
mentioned in this mailing list before.
Looking for the possible cause of the problem, in the list of changes
made for Athena in the latest version of Demeter I found the following:
"Fix a problem processing keV data when using Larch (Thanks to Juan de
la Figuera) (See issue #42)"
May it be that these modifications are responsible for the observed
import bug? (just a guess)
I apologize in advance for repeating myself here, but it really pains me to see people still using the very out-of-date ifeffit backend.
Larch's XAS Viewer can read the files posted just fine (well, 50 unlabelled columns is never "fine" -- you really should complain to the folks generating these files). It does prompt to convert energies in keV to eV, and it doesn't lose any data points doing so. Among other features, it can read and write Athena project files. It may not do everything Athena does, but it does most things, and a few things Athena does not.
