Detailed Description

These functions are for calculating variables used by the MVA calibration.

These functions are for building the maps of functions.

The user can use the functions

• egammaMVAFunctions::initializeElectronFuncs
• egammaMVAFunctions::initializeUnconvertedPhotonFuncs
• egammaMVAFunctions::initializeConvertedPhotonFuncs the will return an unordered map with key a string, corresponding to the variable to be computed and as a value the function, with signature float(const xAOD::Egamma*).
