STAR Flow, Chirality and Vorticity PWG

[subhash <subhash AT rcf.rhic.bnl.gov>]

Dear Priyanshi,

Thanks for the updated slides. I have a few additional comments:

slide#4: 1.3 B events, I assume this is combined Ru+Zr. Then the 50% 
statement is not true. In total we have around 4B events.
Can you update the STAR detector, we also have EPD for this dataset.
slide#11: To what extent the NCQ scaling holds, 10% or less, can you 
mention?
slide#12: In the bullet can you mention the deviation is around 2% 
level? It is seen for KShort too.
You prepared a similar plot with charged hadron v2 ratio, can you keep 
it in back up.
slide#13: Mention that the uncertainties in the ratios are combined 
systematic and statistical.
slide#15: 3rd bullet, mention NCQ scaling holds to XX%
4th bullet, mention that Elliptic flow ratio in isobar species seems to 
show a deviation of XX-XX%
5th bullet: You can split into two observations in low pT and high pT.

Thanks and regards,
Subhash


Thanks for addressing my suggestions.
