STAR Flow, Chirality and Vorticity PWG

[Prithwish Tribedy <ptribedy AT rcf.rhic.bnl.gov>]

Dear Chengdong, Sharang and Yue,
 Please include the comments I sent in the previous email.

Also note that I had a typo in my suggested revision.

I meant :

"along with new results on $v_2$ elliptic flow for light nuclei."

 instead of :

"along with new results on elliptic flow ($v_2$) for light nuclei."

Best,
Prithwish
