[Wien] Relevance of "Edge Energy" in telnes3

Telnes3 needs an "Edge Energy". Based upon a quick test I just did, it
looks like this might be used as a scaling for the energy "somehow"; the
results with an oxygen edge (no core hole) when I use 500eV versus 505eV is
about 1%, i.e. it looks like a 1/E term.

Is this right? If it is, then it is not quite correct as it should, I
believe, be E_core-E_Fermi.

Related, I assume that the origin is E_core-E_Fermi. As a general comment,
this is not "right" for EELS. The convention is to use the energy for the
x-axis (unlike UPS etc).
