[G14_run] G14_run Digest, Vol 31, Issue 11

Mon Apr 14 21:20:32 EDT 2014

Hello Eugene,

Thank you for your comments. In the new file, I cleaned the e-/e+ in the pion events, and add a x-y cut from using MVRT bank, but there are still this low losses bands for all three particles. Could you take a look at the new file below?

Thank you,
Peng
