STAR Flow, Chirality and Vorticity PWG

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

Hi Roy, Niseem,
 The sentence "Not an indication for the absence of the CME" is not 
clear. Do you mean there could be CME in individual Ru and Zr systems 
but the B-field difference is not large enough to make R_2 ratio above 
one? I think such a statement should be rephrased and is better suited 
for slide#16 and not on slide#13 and slide#14 as they are not direct 
conclusions from the plots on slide#13 and slide#14.

Best,
Prithwish
