1) NPE updates by kunsu
slide 2: both Xiaozhi and Kunsu applied Vz, Vzdiff, V(0,0,0) cuts 
slide 4-5: Xiaozhi applied TOF and BEMC cut to TOF electron 1<pT<4, while Kunsu only applied to 1.2<pT<4. This explains the difference at 1<pT<1.2. For pT>1.2, we will check cuts between Kunsu and Xiaozhi by comparing outputs from one picoDst file
slide 6: Kunsu will recalculate eta/pi0/gamma normalization and compare with Xiaozhi
