Update 01.16.2018 -- Run 9 Embedding: Z Vtx., dE/dx, and track/tower eta-phi comparisons

Continuing the comparison between run 9 data and run 9 embedding, the plots below were created without requiring a trigger in data or embedding unless otherwise noted.  The details of the trigger definitions (pi0 in data and the charged hadron in embedding) can be found in this post:

Something I didn't mention in that post were the QA cuts applied to tracks and towers.  All tracks (in both data and embedding, of course) used are required to satisfy these requirements:

  • Nfit > 15
  • Nfit/Nposs > 0.52
  • dca (global) < 1 cm
  • |eta| < 1
  • pT > 0.2 GeV/c.

And all towers used are required to satisfy:

  • Etwr > 0.2 GeV (before hadronic correction)
  • Etwr > 0.2 GeV (after hadronic correction)
  • |eta (detector)| < 0.9.

And the plots:
