The signal plus background region, $|\Delta\eta|< 0.6$ (green points), the region which is background-dominated on the \ns, $0.8< |\Delta\eta|< 1.2$ (black points), and the RPF fit to $|\Delta\phi|< \pi/2$ (blue band) to the region which is background-dominated on the \ns for \pttrigrange{20}{40} jets correlated with \ptassocrange{1.5}{2.0} hadrons from 30-50\% centrality collisions on the top panel. The middle panel shows the quality of the RPF fit to the region which is background-dominated on the \ns, (data$-$fit)/fit. On the bottom panel are the RPF corrected correlation functions, with the uncertainty from the background fit (red band), and the correlated uncertainty (green band)
