STAR Flow, Chirality and Vorticity PWG

Dear Roy,

CW mainly shows the results of two changes to the R-correlator
 1) characterizing each event by the average of two subevent versus including 
each subevent value separately
 2) normalizing the in-plane and out-of-plane distributions separately.
As well as studying a change to the event-plane resolution correction.

Does one or more of those changes remove the "basic rudiments of the 
R-corrleator” , and if so, can you discuss why that feature is key to giving 
sensitivity to CME signal?  Or is there something else that is the key that 
CW’s changes destroy?  
Please explain.
Thanks,
-Evan
