STAR Flow, Chirality and Vorticity PWG

[ShinIchi Esumi <esumi.shinichi.gn AT u.tsukuba.ac.jp>]

Dear Rishabh
I’m questioning the same thing to everyone yesterday in the special pwg 
session, 
it looks like you also have the similar problem in your re-centering 
calibration, as we 
still see about a half of the 1st moment of the non-flatness even after the 
re-centering 
calibration in your page 8, which tells me there is some problem in the 
method. You 
could look at the Priyanshi’s slide page 7, where we only see the higher 
order contributions 
than 1st order moments in a remaining non-flatness after the re-centering 
calibration, 
that is what is supposed to be, although the formula in the page 6 has some 
issues. 
So please make sure your re-centering correction is OK or not. It is flat 
after the final 
Fourier shift correction, so that the final results might still be OK, but it 
would be better 
to do it right. In stead of re-centering the q-vector, which should be done 
in event-wise, 
one can do an inverse weighting factor correction (track-wise) with measured 
azimuthal 
distribution. You can go back to the famous "flow bible" from Sergei and Art 
in '96. 
Best regards, ShinIchi
