Two-particle angular correlation functions as a function of $\Delta\eta$ and $\Delta\varphi$ in pp collisions at $\sqrt{s}=13$ TeV for various multiplicity classes selected with the Midrapidity Multiplicity Estimator and characterised by the mean number of corrected tracks, $\langle N_{\mathrm{ch}}\rangle$ ($|\eta| < 1.0, \, p_{\rm T} > 0.2  \mathrm{GeV/}c$), with the minimum-bias multiplicity at $\langle N_\mathrm{ch}\rangle=11.3$. All correlation functions are shown for 1 $< \it{p}_{\rm{T, assoc}} < \it{p}_{\rm{T, trig}} < $ 2 GeV/$c$.
