The \pt-differential invariant cross section of electrons from heavy-flavour hadron decays in p--Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV. The statistical uncertainties are indicated for both spectra by error bars and the systematic uncertainties are shown as boxes. The published result is shown for 0.5 $< $ \pt $< $ 8 \GeVc , and the measurement using the EMCal trigger is shown up to \pt = 20 \GeVc.
