W-ana chart flow 1

in-memory event structure filled by W-algo ver 4.1

event tree

1. eveID
2. trg
   • bx7,bx48
   • l2bitET,l2bitRnd,L2Result
3. bemc raw hits

   1. BTOW : adc[4800], ene[..], stat[..]

   2. BSMD : adc[2][18000], stat[][]

4. {vertex} list
   1. id, z
   2. {eleTrack} list
      1. isMatch2CL, isNearJet, isAwayJet (expect 1,0,0 for W-electrons)
      2. pointTower
         • id, R(3D)
         • iEta, iPhi (L2 convention)
         • glMuTrack (pointer), primP (3D)
         • jetTPCPT, awayTpcPt (summed)
         • { EMC_cluster} list
         1. cluster (the electron info, summed over 2x2 towers)
            • energy, ET, adcSum, position (3D)
            • nTower, iEta, iPhi (last 2 use L2 convention)
         2. cl4x4 : type EMC_cluster, summed over 4x4 towers
         3. jetEmc : type EMC_cluster, summed over 20x20 towers
         4. awayEmc : type EMC_cluster, summed over 20-phi & 40-eta towers
