Hello Sooraj,

For the pT dependence, I don't have an answer yet.
But for the centrality bins, as I shown in the slides it has consistent
result(same page).
As you mentioned, J/psi has a huge acceptance effect, and this
acceptance effect will affect pT dependence more than the centrality
dependence due to kinetic acceptance. We agree to not show the pT
dependence in the SPIN2023. But in any way, we can revisit this after
the conference if you want.
