[Ifeffit] Re: Athena Suggestions

[Bruce Ravel]

Hmmm... I tried what you did, Matt.  I exported mu(E) from Athena for
both data groups and then did the e0 determination by hand.  This
happened:

  Ifeffit> read_data (gadowee.xmu, group=gad, type=xmu)
  Ifeffit> pre_edge(gad.energy, gad.xmu, find_e0=1)
  Ifeffit> print e0
        10372.5980
  Ifeffit> read_data (gam.xmu, group=gam, type=xmu)
  Ifeffit> pre_edge(gam.energy, gam.xmu, find_e0=1)
  Ifeffit> print e0
        10374.0900

The first e0 value is different from the one you just reported and the
same as Athena tells me.  And I did not get the "out of order"
message.

I'm confused.

And how!
