The luminometers, with the exception of DT and RAMSES, were calibrated using the vdM method, with data collected in LHC Fill 9639. The uncertainties for the total integrated luminosity arise due to sources in the calibration method and also due to possible nonlinearity and detector instabilities over the year. In the calibration part, the main uncertainty arises due to possible XY-factorization bias, while for the integration part the dominant source is linearity. The final value for the integrated luminosity delivered for this dataset is 124.0 1/fb with a preliminary uncertainty of 1.6\%.
