I don't think so, but I'll take another look -- to get E/p to be at 1 was altering my coefficients by lowering each value by 5% or so (based on how E/p looked, I fudged the coeffs to get the peak closer and closer to 1)<br>

</div>I agree, the trend in the plot isn't what I expected. At one point you<br>
had some corrections in your code to get E/p centered on 1 for all<br>
energies -- are you sure those (old) corrections aren't still being<br>
applied somehow?<br>
