$p_{\rm T}$-differential inclusive electron $v_{\rm 2}$ at mid-rapidity in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV measured in the centrality classes: 0-10% (left), 10-20% (middle) and 20-40% (right). The symbols are placed at the centre of the $p_{\rm T}$ interval whose width is shown by the horizontal error bars. The vertical error bars and open boxes represent the statistical and systematic uncertainties, respectively. Results with the event plane and scalar product method are reported with black and red markers, respectively. In the 10-20% and 20-40% centrality classes the results obtained with the EMCal trigger are reported with open black markers.
