14 Calibration study α=0.4 This is interesting. It appears that a linear calibration does not work as well as a calibration attenuated by a power… rpc/PS_pion/PS_summary_alpha.kumac runs calib_1.f

15 Positive beam rpc/PS_pion pion_2.f pion_11_pos.kumac Event selection all: 1 cluster in layer 0 with at most 3 hits electrons: C1 = C2 =1 and BC < 8 pions: C1 = 0 and C2 = 1 and BC<8 and R > 2.0 protons: C1 = 0 and C2 = 0 and BC<8 and R > 2.0 muons: N > 10 and C1 = 0 and C2 = 1 and BC>20 and Hits in last 2 layers and r<2.0 Run
