Update 05.17.2019 -- Run 9 pp: Checking Efficiency When Using Different Nfit Cut And When Using All Tracks

[Recorded on 05.21.2019] Continuing on with some checks after this post:

https://drupal.star.bnl.gov/STAR/blog/dmawxc/update-05162019-run-9-pp-using-different-delta-phi-track-efficiency

First, we wanted to check what happens when we use Nfit > 12 vs. when we use Nfit > 15.

The two efficiencies are consistent, and the Nfit > 12 case being slightly but systematically higher (which is to be expected). Next, I wanted to check what happens when I calculate the efficiency using all tracks (not just recoil tracks).

So -- reassuringly -- they are consistent.
