[Frost] eloss update

[Steffen Strauch]

Dear Brian,

I ran my code (pi+ n channel) with your updated energy-loss routines.  
The results are now added in the collection at (page 3):

The latest results are different from the previous ones. It seems that  
the Delta Missing Mass distributions are more flat over a wider range  
in angles. That's good. Very nice is the significant improvement of  
the missing mass resolution. Earlier, the energy-loss correction  
worsened the missing-mass resolution. This is now fixed. However, at  
the very backward angles (in c.m.) the neutron missing mass is still  
substantially off. With 10 MeV - 20 MeV, I wonder if this is energy  
loss or not something else. Particularly, as these effects are present  
at all energies.

Thanks for your work,
Steffen
