Previously, I did not run over all the embedding files, which caused the improper application of the partonic pT bin weighting.  The plots below now include all embedding files and proper implementation of the weighting, which also included excluding low-count, heavily-weighted partonic pT samples.  The procedure is otherwise the same as before: https://drupal.star.bnl.gov/STAR/blog/skoby/run-11-pp-500-gev-vs-pt
Attached below is version 9 of my talk, where I've updated the top plot on slide 14 with Figure 3 and update the left plot on slide 16 with Figure 2.  Figure 1 is not in my talk.

Figure 1:  matching ratio

Figure 2:  <x> vs pT

Figure 3:  (quarks/partons)_biased/(quarks/partons)_unbiased
