Update 03.15.2019 -- Run 9 embedding: away-side detector-level pTtrk distributions, embedding vs. data

Below are the pTtrk distributions from embedding (Pythia6), data, and Pythia8.  The simulations, embedding and Pythia8, are at the detector-level.  The Pythia8 detector-level was created using the parameterization of the Run 9 response.

This is good. The embedding does a very good job of describing the data, and Pythia8 does an okay job.
