Public Methods

 ElectronMatrixManager (int randSeed, MsgStream &log)
virtual ~ElectronMatrixManager ()
vector< double > getVariables (const TrackTrajectory &, HepMatrix &usedMatrix) const
 returns smear variables and correlation matrix corresponding to given track trajectory


Private Attributes

Detailed Description

Used by tracksmearer to provide smear matrices corresponding to given track trajectories.

It reads a flat file containing smear matrix data and creates a BinData object for every eta/phi/pt bin.
