1) Systematic uncertainty of J/psi in pAu - Yanfang Liu

• slide 3, for pt bin of 1-2 GeV/c, the invariant mass distribution is background subtracted, should not use likelihood but least-\chi^2. For pt bin of 3-4 GeV/c. the \chi^2 looks too large, need to double check if there is something wrong. 
• slide 4, for pt bins of 6-8 and 8-10 GeV/c. The fit fails. Try to use better initial value for the parameters. 
• slide 5, the change of the fit range is too much. For 0-1 and 1-2 GeV/c, better use 2 order pol instead of 4th order pol
• slide 9, for 0-20% centrality, the deviation always on the same side. But need to judge after implementing the suggestions above.
• Agreed to not shown the pt spectra for the min. bias from this analysis but Takahito's preliminary. Plan to show the pt spectra in different centrality in the QM talk.

2) Systematic uncertainty of single electron in Au+Au with HFT - Matthew Kelsey

• S4, try to get the reference of the double ratio by assuming the charm and bottom has the same suppression.
