I found a mistake in my code. The y axis was labeled "delta E", which is 
supposed to be the difference of energy before and after correction. But 
the histogram was filled with "delta momentum". I produced a correct 
histogram and attached (eloss.png).

To solve the issue that there are multiple bands in the histogram of 
energy loss vs. momentum as shown by Dao and Peng, I generated protons 
and pions of various momenta, polar angles, and vertex positions. I 
attached a pdf file to demonstrate them. As a summary, the polar angle 
dependence of the energy loss produces the multiple bands.
