[Ifeffit] Trouble with fitting with Arthemis

I looked at it, and everything works--there's no corrupted data; it's  
just having a hard time getting a decent fit. If you guess multiple  
parameters you'll see it does manage to find some kind of fit, but  
it's poor.

Your data and background subtraction look acceptable, so that leaves  
the model. Perhaps you don't have platinum metal. After all, the files  
are named PtAl--if there are a lot of Pt-Al near neighbors, and you're  
not accounting for them, that could explain why the fit fails.
