STAR Flow, Chirality and Vorticity PWG

Dear Nasim and convenors,

Thank you for your suggestions and comments. I have updated my plots 
accordingly. Kindly find the updated slides at the following links:

Preliminary request:

In the previous PWG meeting, I had shown the phi v2 using ph-psi method 
where we saw some fluctuations in few points. I've now used invariant 
mass technique for phi mesons and added phi-psi method as a systematic 
check. This seems to have resolved the fluctuations.
Also, I implemented the Barlow check and added the systematic 
uncertainties to the ratio plots as suggested by Prithwish.
Moreover, I've added all (anti-)particles for the ncq scaling as 
suggested in the PWG meeting.

Ans: I had quoted an average systematic error percentage over all pT in 
min bias. Due to fluctuations in a few pT bins, the error was larger. 
Having implemented the above mentioned changes, the average systematic 
error is ~4% now for phi mesons.

Ans: Thank you for pointing this out. Having implemented the above 
mentioned changes, these issues have been resolved.
The comparison of Ks0, phi, lambda in both systems has been shown in 
back-up slide (page 27) of the preliminary request presentation.

Kindly let me know your comments and suggestions.

Thanking you

Sincerely,
Priyanshi
