Here is a list of several quantity definitions used in the W codes:

• ET - defined in the code St2011W_algo.cxx (near line 816)
  

  • float Rcylinder= mBtowGeom->Radius(), Rcylinder2=Rcylinder*Rcylinder; 

          float ene= wEve->bemc.eneTile[kBTow][softID-1];     //BEMC energy

          if(ene<=0) continue; // skip towers w/o energy

          float adc= wEve->bemc.adcTile[kBTow][softID-1];

          float delZ=positionBtow[softID-1].z()-zVert;

          float e2et=Rcylinder/sqrt(Rcylinder2+delZ*delZ);

          float ET=ene*e2et;
