Electron performance measurements with the ATLAS detector using the 2010 LHC proton-proton collision data

Detailed measurements of the electron performance of the ATLAS detector at the LHC are reported, using decays of the Z, W and J/ψ particles. Data collected in 2010 at $$\sqrt{s}=7\mbox{~TeV}$$ are used, corresponding to an integrated luminosity of almost 40 pb−1. The inter-alignment of the inne
