Thanks Fan

I'm making progress.

Now the spectra is not as ragged but the spectra does not match what I put in, see

http://sd-www.jhuapl.edu/ACE/EPAM/ArbHist.htm

Although I put in a integral spectra it seems like the created spectra is not integral, it's differential. Thats fine, I can work with that. When I integrate the spectra I get a good match with E> ~5 MeV but below that it does not match what I put in. Any suggestions?

The macro is below:
