Per-trigger associated yields of the NS (left) and AS (right) peaks for $4 \pt^{\rm{e}} 12$~\GeVc as a function of $\pt^{\rm{assoc}}$ in Pb--Pb collision centrality classes 0--10\% and 30--50\%, compared to those obtained from minimum-bias pp collisions. The statistical (systematic) uncertainties are shown as vertical lines (empty boxes). In some $\pt^{\rm{assoc}}$ intervals, the AS yield is consistent with zero within one standard deviation of statistical and systematic uncertainties added in quadrature. For those intervals, upper limits on the yields for 68\% and 95\% confidence levels are evaluated, and are shown with arrows and boxes, respectively.
