The (a) near-side and (b) away-side yield ratios vs \ptassoc for \pttrigrange{20}{40} full jets of 30-50\% centrality in \PbPb collisions. The bands correspond to the background uncertainty, which is non-trivially correlated point-to-point . The systematic uncertainties coming from the shape uncertainty of the acceptance correction cancel out for the ratios. Points are displaced for visibility. Data are compared to calculations from JEWEL  with and without recoil particles
