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 reconstructed tracks, $\langle N_{\mathrm{ch}}\rangle$ ($|\eta| 1.0, \, \pt > 0.2  \mathrm{GeV/}c$). All correlation functions are shown for 1 $\it{p}_{\rm{T, assoc}}\it{p}_{\rm{T, trig}}$ 2 GeV/$c$.
