1. Configuration


mEEclusters=new StMyClusterMaker("mEEclusters", mEEanalysis, mMuDstMaker );
mEEclusters->setSmdSeedEnergy( 3.0/1000.0 );
mEEclusters->setSmdMinimumEnergy( 0.5/1000.0 );
mEEclusters->setSmdMaximumSize(4);
mEEclusters->setSmdMinimumStrips(5);

mEEclusters->setSeedEnergy(2.0);
mEEclusters->setMinimumEnergy(0.5);

mEEpoints=new StMyPointMaker("mEEpoints",mEEanalysis,mEEclusters);
mEEpoints->setSplit();
mEEpoints->setSplitMinimumET(6.5);

After applying the CPV cut:

... approximately 100 pi0 --> 2 gamma events in mass window.
