NAME:     CaloClusterUpdate.h
PACKAGE:  offline/LArCalorimeter/CaloclusterRec
 
AUTHORS:  H. Ma, S. Rajagopalan
CREATED:  Nov, 2000
 
PURPOSE:  Recalculate the total energy, eta,phi of a cluster.
      This should be called after all corrections to individual 
      samplings are done. 
 
      energy = Sum of energy in all sampling
      eta = average of eta1 and eta2, weighted by energy and
                relative resolution.  
        This needs to be tuned. 
      phi    = phi of second sampling. 
 
Base class: CaloClusterCorrection (tool)
 
Atrecon Orig: emreco/qetamod.F
 
Updated:  May 10, 2000    (SR, HM)
          Migrated to Athena Framework from PASO
 
Updated:  Jan 5, 2001    (HM)
          QA. 
 
Updated:  May 5, 2004    (Sven Menke)
      base class changed from algo to tool
 
Updated:  March, 2005    (Maarten Boonekamp)
      moved to CaloClusterCorrection
