[Ifeffit] Ca EXAFS with Ge220 or InSb111 (Lisa Bovenkamp)

I found Ca EXAFS files on my data directory which go out to 600eV above the edge, done using Si111.
What's the symptom of the failure with InSb?  Could harmonics be the problem?  If there's something
mechanical going on with the mono such that you go through the max of the rocking curve, then as
you go through that max, you get more harmonics, which cause normalization failure.
