Dear Barbara,

Thank you for your comments.

Indeed, we derive the yields from R_AA. This is because we directly 
combined R_AA from both channels beforehand, and as a result, deriving 
the yields from the combined R_AA was a straightforward method for us.

Regarding your concern about the treatment of uncertainties, these are 
handled using a simple error propagation principle, given that we are 
only multiplying R_AA by some constants. The systematic uncertainties 
include signal extraction, tracking, and particle identification (PID) 
uncertainties, and they do not incorporate any global uncertainties.

Best,
Ziyang
