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:
