description Improvements to the luminosity calibration performed using the ATLAS detector at the LHC during pp collisions at sqrt(s) = 7 TeV are presented. Updates to previous ATLAS luminosity results are detailed based upon new luminosity calibration data, improved determinations of the LHC bunch currents, and revised estimates of systematic uncertainties. The central value of the ATLAS luminosity scale is found to be 3.6% lower than the previous result, while the relative uncertainty on the luminosity scale is determined to be +/-3.4%.
