In Run 1, the luminosity measurement at CMS was based on the HF occupancy measurement (HFOC). Details on the systematic uncertainties for run 1 corresponding to the normalization constant can be found in PAS LUM-13-001.
The luminosity is calibrated using separation scans first pioneered by Simon van der Meer at the ISR. These "van der Meer scans" allow for determination of the absolute luminosity as a function of beam parameters and so can be used to develop a calibration for the individual luminometers. For more documentation on the procedure and its systematic uncertainties, please see the Lumi POG home page.
The raw data used to generate these plots (pp runs at nominal energy only) can be found in CSV form here.
These plots show the measured luminosity delivered by the LHC to CMS (blue) and recorded by CMS (orange) during stable beams and for proton-proton collisions at a 13 TeV center-of-mass energy in 2018. The delivered luminosity includes the time from the start of stable beams until the beam is dumped by the LHC (or stable beams end for other reasons, for example for beam studies). Note that the special runs at injection energy (450 GeV) are not included in these plots.

Average pileup in 2018
Mean number of interactions per bunch crossing for the 2018 pp run at 13 TeV, using the online luminosity values. The two plots shown here use the same data but with different values assumed for the minimum bias cross section. The left plot uses the "CMS recommended" value of 69.2 mb, which is determined by finding the best agreement with data and is recommended for CMS analyses. The right plot uses the "LHC standard" value of 80 mb, which is taken from the theoretical prediction from Pythia and should be used to compare to other LHC experiments. |
These plots show the measured luminosity delivered by the LHC to CMS (blue) and recorded by CMS (orange) during stable beams in the lead-lead run at a 5.02 TeV center-of-mass energy per nucleon ("HI run") in 2018. The delivered luminosity includes the time from the start of stable beams until the beam is dumped by the LHC (or stable beams end for other reasons, for example for beam studies).

The delivered luminosity includes the time from the start of stable beams until the beam is dumped by the LHC (or stable beams end for other reasons, for example for beam studies).
