Sumario:This short note reports an extrapolation of the measurement of the lepton charge asymmetry for W bosons produced in proton-proton collisions at sqrt(s)=7 TeV, using data collected by the ATLAS experiment at the LHC corresponding to a total integrated luminosity of 35 pb-1. The results reported here are based on the measurements presented in Ref. [1], modified by removing the selection criteria on the missing transverse energy and on the lepton-neutrino transverse mass. These results are appropriate for graphical comparisons to the other experiments but should not be used for fitting parton distribution functions. The measurements reported in the fiducial ATLAS phase space in Ref. [1] have the smallest theoretical uncertainties from acceptance corrections and should therefore be used for further comparisons with theory.
