STAR Flow, Chirality and Vorticity PWG

Dear Li-Ke,

Thanks for the update.
Can you please mention in your slide (may be on 5 or 6) something like: 
Higher statistics and STAR detector upgrades (better EP resolution) 
allow first v3 measurement of several identified particles at BES. Also 
mention typical EP resolution achieved for v3.

I am pushing your slides to star-talks.

Thanks and regards,
Subhash
