GPC members are happy with most of the responses. There are a few items need to be further checked.
- Handling of the 5% systematic uncertainty of tracking efficiency. Currently assigned 5%*sqrt(2) for dN/dy and <pT> and completely canceled out for K*/K- ratio. PAs are suggested to contact the PWG conveners and make sure about the origin of the 5% systematic uncertainty and check whether it is a global uncertainty. And handle it for dN/dy, <pT> and particle ratios in a consistent way.
- The m2 fitting at the highest pT bins do not look good. PAs explained the impact on K* efficiency should be minor due to the kinematic coverage and GPC agree with it. Nevertheless, PAs agree to do some further checks.
- The systematic uncertainty are very different between RMS and (max-min)/sqrt(12) for some pT bin. PAs agree to list the contributions from difference sources to understand the large difference.
- The TOF matching efficiency calculated might be affected by pileup tracks. PAs will check the ZDC rate or #global tracks dependence of the TOF matching efficiency.
Priyanshi reported that the code QA is done.
It is agreed that the further checks would not change the conclusion and presentation of the paper. PAs will release a new version of the paper draft, GPC will then start work on the text.
