0001 This module is meant to study the sphenix emcal pi0 reconstruction efficiency.
0002 Single pi0's are fired into the emcal over a range of energies (0.5-20)
0003 The output from the Fun4All simulation is then analyzed by pi0Efficiency.cc/h
0004 And output histograms are generated containing information on the reconstructed
0005 invariant mass and energy with different minimum energy cuts.
0006
0007 Truth level information on the parent pi0's energy as well as
0008 the decay photons energy asymmetry and opening angle as a function of the truth
0009 pi0 energy are also available
0010
0011 The offline directory contains a single macro that takes in the output file
0012 as its sole input and compute the efficiency.
