Update 02.12.2018 -- Run 9 Purity: STAR vs. PHENIX Data
Below is a plot comparing R calculated from STAR data to PHENIX data for a variety of systems. The STAR pp 200 GeV points are "inclusive gamma-rich" triggers as defined in this post:

With the primary tracks required to have pTtrk = 1.2 - 20 GeV/c and zTtrk = 0.2 - 0.3. The STAR pp 200 GeV points can be viewed on their own in this post:

Update [02.14.2018]: The binning on the plot was incorrect. I've replaced the old plot with the correct plot.
Update [02.16.2018]: The errors on the STAR pp points were incorrect. I've replaced the old plot with the correct one, and have listed the STAR pp 200 GeV (inclusive gamma-rich) values of and their statistical errors below. The systematic errors are 10% of R. The values in the parenthesis indicate the center of the corresponding trigger pT bin.
