Example of the impact parameter distributions used in the TPC--EMCal analysis in 0--10\% Pb--Pb collisions at $\sqrt{s_{\rm{NN}}} = 5.02 {\rm TeV}$. The hadron contamination (red), photonic electron (purple), and inclusive electron (black) $d_{0}$ distributions are shown in the left panel. The right panel shows an example of a fit with the two template approach.
