 Azimuthal correlations between heavy-flavour decay electrons and charged particles, for high-multiplicity and low-multiplicity p--Pb collisions, after subtracting the baseline (see text for details) for $2 < p_{\rm{T}}^{\rm e} < 4$ GeV/$c$ and $0.3 < p_{\rm T}^{\rm{ch}} < 2$ GeV/$c$. Statistical uncertainties are shown as error bars. The statistical uncertainties on the baseline subtraction are represented as boxes at $\Delta\varphi \approx 5$.
