Hi Jiangyong,

Thanks for the nice comments.

    Please find the updated abstract at the same link,

I think that both sets of results will guide the extraction of \eta/s. I rephrased the abstract to reflect the value of each set of measurements.

Thanks,
Niseem

Hi, Niseem,

Nice abstract

1. Please mention STAR in title

2. The scope of the abstract is quite broad, I would suggest you to focus on the C2(Δη,Δφ) in BES.  Since there might still be systematic checks to be done, for example how stable are the results if you vary the pair cuts, this aught to be one sources of uncertainty.  Also the vn-pT correlation is a bit distraction to your eta/s focus, I suggest you just show your previous prelim results.

Cheers,

Jiangyong

For your comments,

It is not clear what this new observable is C2(Δη,Δφ) does not clearly indicate that you're measuring transverse momentum correlations.
>> It's written that C2(Δη, Δφ) is the “longitudinal two-particle momentum correlations”


Do you think you'll be done with systematics by CPOD
>>The standard systematics i.e. tracks and events variations exist, currently along with others we are working on the systematics associated with the extraction of the \eta/s

I remember you looked at \rho for three energies:
https://drupal.star.bnl.gov/STAR/system/files/Flow_PT_5.pdf
Did you look at all other energies for 200-11.5 GeV, if not do you plan to update soon ? Or I missed it?
>>I’m working on including some of the lower beam energies, however, I rephrased the sentence to reflect the energy range for the different measurements

Thanks,
Niseem
