STAR Flow, Chirality and Vorticity PWG

["Wang, Fuqiang" <fqwang AT purdue.edu>]

Hi Gavin,

Thanks for sending the numbers. Let me understand a bit more. Take 14 GeV results using the second-harmonic plane as example. 

Let's say the default is line 56 in the excel:

dca=2cm, nsigma=2.5, norm.range=[1.04,1.05], use integral method, between [-2Gamma,2Gamma], you get rho_00=0.3482.

I see the dca variations to 2.5 cm and 3 cm are line 58 and 63. The changes in rho00 are 0.0004, 0.0005, respectively.

What syst. uncertainty is assigned for dca variation?

I also see the nsigma varitations to 2 and 3 are line 67 and 71. The changes in rho00 are both 0. 

What syst. uncertainty is assigned to nsigma variation?

Best regards,

Fuqiang

Dear Fuqiang,

I have attached the ρ00 values table for the variations used in our systematic error calculation. This table includes the integrated ρ00 from the pT dependent studies for 14.6 GeV with 1st and 2nd order event plane, and 19.6 GeV with 1st order event plane. I have attached the table as an excel and as a text file.

Best,

Gavin

Hi Baoshan,

On s11, you obtain the syst by (max-min)/sqrt(12). I'm a bit wary of that, because one has to be reasonably certain that the variations are truly min to max. Can you compile a table of the rho00 values for all the syst variations?

Best regards,

Fuqiang
