Raw spectrum of electrons from the impact parameter analysis (open circles) compared to background sources (from charm hadron decays, photon conversions, Dalitz decays, and hadron contamination) as a function of $\pt$. The background sources originating from light flavour hadrons were obtained using a MC simulation and re-weighted according to the $\pi^{0}$ $\pt$ spectrum measured with ALICE . The charm hadron decay background was estimated using the charm hadron spectra measured with ALICE . The raw yield after background sources are subtracted is also shown (filled circles). The error bars represent the statistical uncertainties.
