Inspiration for p+Au analysis from old Hard Probes embedding/unfolding procedure

As we prepare to unfold the Run 15 p+Au data with the now bug-free official STAR PYTHIA dijet embedding into p+Au MB background, we look back to what approach was used for the unofficial "internal" embedding used by the Joern Putschke group to have something to show at Hard Probes '20. We think about what if anything will need to change from that approach to adapt it to the current analysis.
