Detailed Description

A tool used by the egammaMVASvc to help calibrate energy for one particle type.

The particle type to be calibrated must be specified by the property ParticleType. The property folder must be set with the path to a folder containig three files:

MVACalib_electron.weights.root
MVACalib_unconvertedPhoton.weights.root
MVACalib_convertedPhoton.weights.root

The ROOT files should have in the following content:

a TH2Poly object named "hPoly". This is used to decide which BDT to use. The x-axis is cluster eta, the y-axis is the raw-accordion-Et in GeV. The BDT that will be used for each event is the one with index equal to the content of the TH2Poly - 1, e.g. const int bin = m_hPoly->FindBin(etaVar, energyVarGeV) - 1. (the minimum value in the TH2Poly is 1)
several TTree named BDTX where X is an integer index (not padded). X here counts from 0. Each TTree has the weights of a BDT and it is the input to MVAUtils::BDT. Alternatively the TTree can be inside a TObjArray named "trees".
a TObjArray named "variables" containing many TObjString, each one for each BDT. Each TObjString is a string containing the names of the input variables for each BDT, separated by ";". The names should be understandable by egammaMVAFunctions::initializeElectronFuncs, egammaMVAFunctions::initializeUnconvertedPhotonFuncs, egammaMVAFunctions::initializeConvertedPhotonFuncs.
a TObjectArray named "shifts" containing many TObjString, each one for each BDT. Each TObjString is a string which represent the formula to compute the shift (used to construct a TFormula). The variables is the Et in GeV after the calibration. The value of the shift is divided by the energy calibrated by the BDT.

On data the property use_layer_corrected should be set to true. In reconstruction this flag is always false. In PhysicsAnalysis it should be set appropriately. When set to true when using the layer energies as input the data-driver-corrected version are used.

◆ getKey()

SG::sgkey_t asg::AsgTool::getKey ( const void * ptr ) const

inherited

Get the (hashed) key of an object that is in the event store.

This is a bit of a special one. StoreGateSvc and xAOD::TEvent both provide ways for getting the SG::sgkey_t key for an object that is in the store, based on a bare pointer. But they provide different interfaces for doing so.

In order to allow tools to efficiently perform this operation, they can use this helper function.

See also: asg::AsgTool::getName

Parameters

ptr	The bare pointer to the object that the event store should know about

Returns: The hashed key of the object in the store. If not found, an invalid (zero) key.

Definition at line 119 of file AsgTool.cxx.

◆ getName()

const std::string & asg::AsgTool::getName ( const void * ptr ) const

◆ inputHandles()

◆ msg_level_name()

const std::string & asg::AsgTool::msg_level_name ( ) const

inherited

A deprecated function for getting the message level's name.

Instead of using this, weirdly named function, user code should get the string name of the current minimum message level (in case they really need it...), with:

MSG::name( msg().level() )

This function's name doesn't follow the ATLAS coding rules, and as such will be removed in the not too distant future.

Returns: The string name of the current minimum message level that's printed
