STAR Flow, Chirality and Vorticity PWG

Dear Li-Ke, PAs,

Thanks for your reminder. I have read the materials, they are in good 
shape. I sign-off once the following comments are addressed:

Paper draft summary: I am of the opinion that at these low energies 
several effects are inter-twined, like shadowing (making v2 negative), 
transported quarks etc. The breaking of scaling can be due to multiple 
factors, can we use it as evidence for onset as mentioned in the 
summary. Especially, from Fig. 4, the p/K is close to 1 in data 3.9 & 
4.5 GeV, and you argued that JAM can't reproduce this  because JAM don't 
have partonic interactions. But the JAM underestimate both the ratios 
for all energies we measured by several sigmas. So I don't get the 
argument you are making, especially line 189-onwards. Do you have these 
ratios from other models, like SMASH, AMPT-string melting?

Minor suggestions:
Fig. 1: You can probably mention the box inside figures are the used 
acceptance in the caption.
Fig. 2: please remove "STAR preliminary" level. Can you try making JAM 
and corresponding beam energy data in similar color. I was bit 
struggling comparing between data/model in this busy plot.

Thanks and regards,
Subhash
