The h--$\Lambda$ (top) and h--h (bottom) $\Delta\varphi$ distributions for each multiplicity class with $4.0 < p_{\text{T,trig}} < 8.0$ \GeVc and $1.5 < p_{\text{T,assoc}} < 2.5$ \GeVc, with statistical (systematic) uncertainties shown as vertical lines (shaded boxes). The multiplicity classes are plotted from the most central (left) to the least central (right). The UE estimate with $v_{2}$ assumption is shown as a dashed line.
