1 ) PYTHIA with StRoot (20k events each): 
    ckin3 = 2 GeV/c
    PYTHIA filter           :  π⁰ energy in each of the eight quadrant within 40-45, 80-85, 120-125 GeV in pseudorapidity 2.6-3.5

2) Single Particle  (20k each): 
 π⁰ 's with energies at 40, 80, 120 and 160 GeV with the pseudorapidity 2.6-3.5 are thrown uniformly. Comparisons of energy for jets made of photons(RED), clusters(GREEN), and towers(BLUE) shown in the figures. For eta and phi distributions, a solid black line indicates distributions for the  incident π⁰'s in the detector.

The region setected are mostly in the large cell region. It is showing that recontruction of photons are not good in the region when it is 80GeV and above. At 40 GeV double peak shape seems to be starnge behavior.
