Detailed detector simulations of the Barrel Calorimeter and each single module have been performed. As input data for the detector simulations the output of the genr8 phase-space distributed event generator have been used. The simulations show that the Barrel Calorimeter contains about 97% of the shower energy produced by the eta and pi^0 decay photons.
The energy deposited in 1cm^2 segments of the BCal module is
simulated for readout purposes.
