Maybe useful to you. However, I would advise to do a fluorescence scan over the range given in the graph and then use chooch to provide the precise energies for your peak and inflection. If you have a large crystal don't expose all of it when you do the fluorescence scan but rather reserve a 'fresh' piece to do your actual data collection.
