1) QA of run16 Au+Au@200GeV SL18f- Jan Vanek
Please show the nHits distribution for different pt bins to see if there is any different in track quality cuts.
It was note by Sooraj that there was a slight different in the evaluation of B-field used for calculation of the momentum which could explain the observed effect:

and
p { margin-bottom: 0.25cm; line-height: 120%; }a:link { }
p { margin-bottom: 0.25cm; line-height: 120%; }a:link { }It would be good to normalize the shown plots per event.
2) K and pi PID efficiency for D0 in d+Au - Lukas Kramarik
There is rather large decrease of the dE/dx mean for kaon with pt, very different from run 15, which needs to be understood.
3) Update on electron purity for Run14 single e analysis - Matthew Kelsey
On slide 4 the sWeighted data not only remove the electron contamination, but the distribution also seems generally narrower. This could be checked by increasing/decreasing the background under the Ks peak.
