STAR Flow, Chirality and Vorticity PWG

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

Dear Prabhupada
I’ve been seeing a reasonable agreement between you and the one from Shaowei 
in the E-mail discussions. If the previous preliminary shown in the last QM 
is consistent 
with your analysis within the statistical and systematic errors, we do not 
have to 
update/modify the previous results, what you are showing now in this slide is 
then 
the one from the previous preliminary? or new results? You mentioned in the 
reply to 
Jiangyong’s E-mail, you seem to exclude systematic errors in one of the 
companion 
plots, however the comparison to the models or other data should always 
include the 
both statistical and systematic errors. There are some exceptions where you 
can 
exclude one of them, when you are comparing the exact same data sets or in 
case 
some systematics would cancel etc...
Best regards, ShinIchi
