Re: sampling fluctuations

[Matthew Shepherd <mashephe@indiana.edu>]

Beautiful!  I think I want the bottom right plot of Figure 13.   
Thanks for including the deposited energy sampling fraction, this is  
the relevant term for MC simulations since fluctuations in sampling  
fraction due to losses outside the module are already effectively  
modeled.  For now I will treat the mean sampling fraction as  
constant. Variations only seem to be at the couple of percent level  
and at very low energy.

Thanks Blake!
