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 transformer model in onnx format Since Transformer use cells directly as input, layer calibration will be applied to one of the decorator and another decorator will not have layer calibration applied. 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.

Public members of this function is kept same as BDT for interface consistency.

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::Event 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.
