Dear Xingrui,

Thanks for doing this check and updating figures. For SQM, I agree current approach is fine, I will look forward to your study on reducing background contribution.

Thanks and regards,
Subhash

Dear conveners,

Following our discussions in the last FCV meeting，we exclude the
extract method systematic uncertainty source.

Regarding the estimation of systematic uncertainty from background
contributions, we attempted to employ the method suggested last night.
However, the obtained systematic uncertainty remained consistent due
to the relatively high proportion of Lambda background. Although
further optimization of topological cuts may reduce the contribution
from this background, considering the imminent SQM, we plan to
maintain the current results in this preliminary figures. In
subsequent analyses, we will work on reducing the Lambda background
and updating the systematic uncertainty associated with background
contributions.

Please find the update preliminary figures in the slide page15-18,
and have a look.

Dear conveners,

I would like to request the preliminary on "Lambda global
polarization in AuAu collisions at 7.7, 9.2, 11.5, 14.6 and 17.3 GeV
