Public CMS Data Quality Information

Overview

The quality of data recorded by the CMS experiment is summarized for the LHC Run 1 (2010-2013), Run 2 (2015-2018), and Run 3 period (2022).
The information is provided for proton-proton, lead-lead, and proton-lead collisions separately.
For each period, results are shown, including the cumulative luminosity delivered by LHC, recorded by CMS, and certified as Good for physics analysis. Data are defined as good for physics analysis if all subdetectors, triggers, and physics objects (tracking, electron, muon, gamma, jet, and MET) show the expected performance.
Further details on the luminosity measurements done in the CMS experiment are described in the CMS public twiki page
