STAR Flow, Chirality and Vorticity PWG

Dear Tongzhou
Thank you for the interesting results, I have a few questions. 
Are you request preliminary for all these plots in the slides for APS meeting?

(1) The statistical errors should be given by the number of events, not the 
total 
number of tracks, right? Does the used event statistics reflect the size of 
the 
statistical errors between 54 and 27GeV data? What are the number of events 
used for these 2 data sets? 

(2) The top-middle panel in p5 is a part of same data in p8, right, where you 
have excluded the central events, because of some experimental problems, 
like pile-up etc? Do they have same statical errors on the both pages? If you 
have already systematic error estimation, why don’t you include in other 
pages? 
Do you have convincing reason how you have decided to exclude the high 
multiplicity region? 

(3) The trends for two energies are similar, but the different eta gaps 
approach 
at higher multiplicity for 54GeV, but they cross for 27GeV, do you know why? 
You have used RefMult in the PWG, which is now shown as Nch, are they 
same number? What if you plot and compare them as a function of centrality?

Best regards, ShinIchi
