  - Towers that have at least one hit from a neutral particle are used together with tracks as input for the jet finding algorithm. If a tower has hits from both neutral and charged particles, then we have double counting for the charged particles. '''Solved: calculate fraction of energy from neutral particles in ecal and hcal and then apply this fraction to the smeared ecal and hcal energy.'''
 
- - Current tau-jet finding algorithm seems to be too simplistic. It looks as a simplified version of the tau-jet finding algorithm from PGS. And the latter is reported to have problems:
+ - Current tau-jet finding algorithm seems to be too simplistic:
+   - E_cal = sum of energies of calorimeter towers with ET_tower > 2GeV within DeltaR < 0.15 around jet axis
+   - N_trk = number of tracks with PT_trk > 1 GeV within DeltaR < 0.4 around jet axis
+   - select jet as tau-jet if PT_jet > 10GeV and E_cal/E_jet > 0.95 and (N_trk = 1 or N_trk = 3)

+Should not we implement tau-jet finding in the same way as we implement b-jet finding.
