Update 09.02.2018 -- Run 9 pp: tracking efficiency, systematic error (R = 0.2 jets)
Below are the systematic errors due to the tracking efficiency for R = 0.2 charged jets (for each bin of 'eTtrg'). The tracking efficiency was implemented as discussed in these posts:

And these were the parameters used for the unfolding:
minus 5% | plus 5% | ||||
eTtrg [GeV] | gamma | pi0 | gamma | pi0 | default |
9 - 11 | SVD, k = 9 | SVD k = 9 | SVD, k = 10 | SVD, k = 10 | SVD, k = 11 |
11 - 15 | Bayes., k = 2 | Bayes., k = 2 | Bayes., k = 2 | Bayes., k = 2 | Bayes., k = 2 |
15 - 20 | SVD, k = 20 | SVD, k = 10 | SVD, k = 10 | SVD, k = 10 | SVD, k = 10 |
where 'gamma' indicates 'gamma-rich'. In the default case, the same parameters were used for the gamma-rich and pi0 triggers.
eTtrg = 9 - 11 GeV:
eTtrg = 11 - 15 GeV:
eTtrg = 15 - 20 GeV:
Update [09.04.2018]: it turns out I was doing the direct-photon subtraction wrong (and not even correcting the default gamma-rich distribution!), so all of the plots have been replaced with the correct equivalents. Not to mention, I've changed how the %-differences are visualized: now the lower panel shows the ratio of the variation to the default value.
