EIC Tutorial: Analysis: Glossary

Key Points

Introduction
  • Use xrdfs from within the eic-shell to browse available files from simulations campaigns.

  • Use xrdcp from within eic-shell to copy files to your local environment.

  • Within eic-shell, you can also stream files directly in your root macros.

The Reconstruction Output Tree
  • Output trees contain a lot of information. Take time to explore what is available, identify what you want to try and do, find the relevant branches.

  • The MCParticles branch holds information on generator level particles, critical for use in comparing to what we actually detect!

Analyzing the Reconstruction Output
  • Flat tree structure provides flexibility in analysis.

  • The ReconstructedChargedParticles branch holds information on reconstructed tracks.

Full Chain Analysis
  • There are a few steps to go through before we get to the file we analysed previously.

  • Good for testing, but use simulation campaign output where possible!.

Additional Resources
  • Starting scripts for the exercises are available.

  • Completed (tm) exercise scripts will be available after the lesson.

  • Talk to your colleagues in your WG if you don’t know where to get started. Check the Examples Repository too!
