More Pi0's reconstructed
with SF=50ch/GeV (from MIP calib)

The events taken with ppTrans-1 trigger were sorted according to the trigger: 1000=MinB, 1152= EHT2, 1150=1151+1152+1154=EHT1&2(fast+slow), 0=all events (including FPD-trig).
The params for pi0 reconstruction: seed energy of 0.6 GeV, seed/total energy >0.7, pi0 inv mass cut=0.07-0.22 GeV,SF=50 ch/GeV relative gains from MIPs (for eta bin 1-4) & slopes (1-4).

Six panels below show:
-top left: invariant mass spectrum for all events,
-top mid: energy of pi0, after invM cut =0.05,0.22 GeV
-top right: transverse momentum of pi0, after invM cut
-bottom left: energy shearing Z=|E1-E2|/(E1+E2) of 2 gammas, after invM cut
-bottom mid: opening angle of 2 gammas, after invM cut
-bottom right: pseudo-rapidity distrib. of pi0, after invM cut
Green histos represent mixed events
Red= raw events - mixed events.

Runs used: ~7M event from days 120-130
