class ElectronEfficiencyCorrector : public xAH::Algorithm

This is the algorithm class that applies generic corrections to electrons. At the moment, only data/MC efficiency correction is included (electron trigger SF and others will follow…).

In a nutshell, this algorithm performs the following actions:

  • retrieves an xAOD::ElectronContainer from either TEvent or TStore

  • adds a scale factor (SF) decoration for each electron in the input container calculated via the AsgElectronEfficiencyCorrectionTool in Tools Used

  • the nominal SF and all the systematically-varied ones are saved as a vector<double> decoration for each electron

Note

Bear in mind that this algorithm must be called after ElectronSelector. In fact, the configuration file(s) being used must have the same working point as the one chosen in the selector.

Public Members

std::string m_inContainerName = ""

The name of the input container for this algorithm to read from TEvent or TStore

std::string m_inputSystNamesElectrons

The name of the vector containing the names of the systematically-varied electrons-related containers from the upstream algorithm, which will be processed by this algorithm.

Only electron calibration systematics or any other that create shallow copies of electron containers should be passed to this tool. It is advised to run this algorithm before running algorithms combining multiple calibration systematics (e.g. overlap removal).

bool m_writeSystToMetadata = false

Write systematics names to metadata.
