1) PID efficiency for D+- in Run16 Au+Au@200GeV - Jan Vanek

• slide11, why the HFT ratio increases with increasing pt in embedding, the reason could be not TPC fluctuation in this embedding, will double check
• slide 23, why the PID efficiency drops? it is because of binning?

2) Effect of RC-MC issue for very low pT Jpsi analysis - Wangmei Zha

• slide 12-13, Petr requested ratio plor

3) Number of equivalent MB events estimation for run11 HT2 triggered data - Shuai Yang

• slide 8, question about the systematic uncertainty on these numbers. The answers is we usually don't have systematic uncertainty on these numbers, but have systematic uncertainty on Nbin. 

4) Update on PID efficiencies studies for D0 in d+Au - Lucas Kramarik

• slide 11, the distribution is flat and looks more reasonable.
