Summary

This PR improves the MC handling in jetLundPlane.cxx by making the reco/truth event selection more symmetric and by storing MC event metadata in the MiniAOD tables.

Main changes

  • Require particle-level jets to have a corresponding filtered reconstructed MC collision before filling truth-level tables and histograms (similarly to jetFinderQA.cxx),
  • Store MC event metadata in MiniCollisions (MC collision ID, event weight, ptHard),
  • Enable offline reco/truth jet association through the stored MC collision ID.
