Detailed Description

Normalizing Flows-based correction tool for photon MC shower shape variables.

The tool applies a two-step NF mapping using ONNX Runtime inference:

• Forward model: maps shower shape tenzor -> latent representation (z)
• Backward model: maps latent representation (z) -> corrected shower shape tenzor

The correction is applied to the photon shower shape variables listed in s_ssVarNames (the order should correspond to order in a model).

The ONNX models are provided per-fold via ToolHandleArray, and the fold is selected event-by-event using EventInfo::eventNumber() (optionally including pT).

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.

Returns

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

inputHandles()

msg()

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
