The azimuthal-correlation distribution for $4 < p_{\rm T}^{\rm e} < 12$ GeV/$c$ fitted with a constant function for the baseline (green line) and von Mises functions for AS and NS peaks (grey curves) for different associated $\pt$ ranges in pp collisions at $\sqrt{s}= 5.02$ TeV (top panels) and p-Pb collisions at $\sqrt{s_{\rm NN}}= 5.02$ TeV (bottom panels). The statistical (uncorrelated systematic) uncertainties are shown as vertical lines (empty boxes). The uncertainties of the baseline estimation are shown as solid boxes at $\Delta\varphi \sim -2$ rad.
