To get an idea of how big the corrections are due to the unfolding procedure and if any odd features appear in the unfolding procedure, I've plotted the raw data and unfolded distributions on top of each other for all 3 eTtrg bins for both triggers.  Some of the specifics of the unfolding can be found in this post:

And the plots:

As anticipated, the corrections are very small.  Note that the gamma-triggered distributions have not had the background subtraction yet.

Update [08.28.2018]: to get a more quantitative idea of how big the corrections are, see this post:
