1) Jpsi via the dimuon channel  in Run14 200 GeV (slides 1-33) - Rongrong Ma
a. Slide 7: are the Tpc-Vpd efficiencies the same in MB and dimuon events for 60-80%? Also need to check whether there is any trigger bias factor for 60-80% range.
b. On slide 8, there are several runs around 15152000 having RF different from other runs. Need to check whether they are bad runs.
c. Slide 9: need to understand why the # of MB events are smaller in 60-80% centrality bin. One suspicion is that the centrality calibration was done using prod_low and prod_mid data, while prod_high data are used in this analysis. Need to investigate whether some additional weights are needed for prod_high data.
d. Slide 19: check the significance of the difference between 60-80% and other centrality bins by taking into account the systematic uncertainty. If the difference is indeed significant, need to understand whether the difference can be understood due to for example different vertex resolutions.
e. Slide 21: the difference in LS distributions between same-event and mix-event is probably due to correlated contribution in same-event
f. Slide 29: the bin-counting results seem to be systematically above the fitting results. Is it a systematic effect? Should be the difference included in the uncertainty?
