CERN-LHC. Measurement of the cross sections for inclusive production of W+, W- and Z0 bosons in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data sample used has a total integrated luminosity of 36 pb-1. Data are given for both electron and muon decay channels and for full corrected and within the fiducual acceptance of the experiment. In the tables the second systematic error is the uncertainty on the theory input to the measurement of the cross section.
