Per-trigger dihadron $\Delta\varphi$ angular correlations integrated over the range $|\Delta\eta| < 1.2$ for the lower $p_{\rm T}$ range of associated hadrons, $1.5 < p_{\rm T} < 2.5$ GeV/$c$ (top), and the higher $p_{\rm T}$ range of associated hadrons, $2.5 < p_{\rm T} < 4.0$ GeV/$c$ (bottom). The three multiplicity classes are plotted in increasing order from left to right. All plots for a given associated particle $p_{\rm T}$ have the same axis scale, with offsets set to their respective underlying background estimation. Statistical uncertainties are represented as error bars, while systematic uncertainties are marked as open rectangles.
