Detailed Description

JetBadChanCorrTool.

The energy fraction of dead cells are estimated by jet-level estimator using jet profile. Some cells are already corrected in cell-level using neighboring cells, so this fraction is calculated. The estimation by jet-level for those cells corrected in cell-level is also stored to see the difference or combined the corrections.

BCH_CORR_JET= jet level estimation of the energy fraction of dead cells BCH_CORR_CELL= cell level correction, which is already corrected BCH_CORR_JET_FORCELL= jet level estimation for the corrected cells in cell level

The relation and usage of the moment is jet = jet already corrected in cell level jet x ( 1 - BCH_CORR_CELL ) = jet without cell level correction jet x ( 1 - BCH_CORR_CELL + BCH_CORR_JET ) = jet corrected by jet level estimation jet x ( 1 + BCH_CORR_JET - BCH_CORR_JET_FORCELL ) = jet with cell level correction and corrected in jet level for not covered cells

Member Function Documentation

int JetBadChanCorrTool::correctionFromCellsInJet ( xAOD::Jet j,
const jet::CaloCellFastMap *  badCellMap 
) const [protected]

bool useCalibTool = m_useCalibScale && jet.signalState()==P4SignalStateCALIBRATED;

StatusCode JetBadChanCorrTool::initialize ( void   )  [virtual]

Dummy implementation of the initialisation function

It's here to allow the dual-use tools to skip defining an initialisation function. Since many are doing so...

Reimplemented from asg::AsgTool.

int JetBadChanCorrTool::modifyJet ( xAOD::Jet jet  )  const [virtual]

Method to modify a jet. Returns 0 for success.

Implements ISingleJetModifier.
