Update/Cleanup of the TrigTauRec package
This MR addresses the cleanup/documentation of the TrigTauRec
package, in preparation for the HLT GNTau implementation. This is part of a series of MRs that will be undrafted sequentially.
No HLT Tau Triggers will be used in the low-mu pp or HI data-taking runs, so we can open these MRs now, which are needed before we start validating the new HLT GNTau.
Amongst the most important changes, we can list:
- Cleanup of the
TrigTauRecMerged
algorithm:- Better separated the calo-only reconstruction (for the CaloMVA step), and the
xAOD::TauJet
-seeded reconstruction (for the Precision step). - Removed some unused skeleton code from previous versions. This is a much better clean slate for the soon-to-come changes (3-step tracking, preselections, etc...).
- Added support for monitoring multiple TauId scores.
- Better separated the calo-only reconstruction (for the CaloMVA step), and the
- Updated online TauID score monitoring histograms:
- The histograms' names have been overridden to be the same as in the current Athena release to allow for an HLT Reprocessing validation round with complete reference comparisons.
- After the changes are validated, we'll update the histogram names.
- Added ONNX-based TauID inferences.
- Moved HLT TauID config flags to sub-directories:
- Each algorithm will have a dedicated sub-directory for it's configuration
- The required LVNN-based or ONNX-based infrastructure is automatically loaded and configured based on the config-flags for each algorithm. This allows for quick testing and deployment of new algorithms!
- Moved the
TrigTauCaloRoiUpdater
andTrigTauTrackRoiUpdater
algorithms from theTrigTauHypo
to theTrigTauRec
package, since they are not hypothesis algorithms or tools (this caused some confusion in the past to newcomers). - Added a
README.md
, and descriptive comments to the configuration code of theTrigTauRec
package. - Added support in the EDM for additional TauID scores and WPs.
- General code linting.
The changes were validated by comparing event counts and online/offline monitoring histograms for 10k mc23e ttbar/g*tautau/Ztautau events.
With this last MR, we're ready to deploy the HLT GNTau ID with minimal changes as soon as it's ready
