STAR Flow, Chirality and Vorticity PWG

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

Hi Chunjian, and all

Your nice suggestions are implemented, here is the updated slides

https://drupal.star.bnl.gov/STAR/system/files/QM2022_HaojieXu_v10.pdf

I am still worried about the message from lower panel of ac3 plot. 
Besides the non-flow effect, as I have already mentioned, the 
ac2{3}/v_2{2}^{4} is not exactly the non-linear coefficient.  As it was 
just an approximation, I suggest not to extract any nonlinear 
coefficient at this moment. Or can you directly compare ac2{3} to 
<v_2^{4}> instead of v_2{2}^{4}?

with best regards,
Haojie
