1) Run16 D0 measurements - Xiaolong Chen
a) plot the TPC tracking efficiencies in different centrality bins in one figure to check the centrality dependence for both Run14 and Run16.
b) Slide 7: combining at the raw signal level does not seem to work. Suggest to fit the Run14 and Run16 distributions simultaneously to maximize the statistical power while retaining the difference between the two years. 
c) Slide 9: more discussions are needed if the PA would like update Run14 preliminary results due to the issue in signal extraction. However, this is in principle not allowed and needs to be well thought. 
d) Slide 11: both the centrality calibration and D0 templates do not work for production_2. Need to investigate why this is the case. However, due to the very limited time, suggest to focus on using the first part of Run16 production to carry out the analysis to the end. One can work on production_2 if time allows.
