Detailed Description

ASG selection tool implementing a photon-ID working point based on a BDT score.

This tool provides an interface for photon identification, using a BDT-based discriminant.

It applies:

• a set of preselection requirements (f1 and e277),
• a BDT score cut that depends on (|eta|, Et) bin and conversion status.

The working point (binning and thresholds) is read from a TEnv configuration file

The tool can either:

• compute the score on-the-fly via PhotonBDTCalculator (if allowed and the score decoration is missing), or
• reuse an existing score decoration already present on the photon.

Note

The meaning of the isEM bits is specific to this BDT selector and is documented in this implementation.
