 ====== Luminosity at CMS ====== ====== Luminosity at CMS ======
  
-Summary plots can be found here: +Summary plots of data taking at CMS and the LHC can be found [[https://twiki.cern.ch/twiki/bin/view/CMSPublic/LumiPublicResults|here]]. 
-[[https://twiki.cern.ch/twiki/bin/view/CMSPublic/LumiPublicResults]]+ 
 + 
 +===== Calculate the integrated luminosity ===== 
 + 
 +For a given dataset, you can calculate the luminosity yourself with the ''brilcalc'' tool described [[https://twiki.cern.ch/twiki/bin/view/CMS/TWikiLUM|at the Lumi POG]] and [[https://cms-service-lumi.web.cern.ch/cms-service-lumi/brilwsdoc.html|in the manual]]. 
 + 
 +You need a JSON file that contains all the runs you want to include: 
 +<code bash> 
 +brilcalc lumi -b "STABLE BEAMS" --normtag /afs/cern.ch/user/l/lumipro/public/Normtags/normtag_DATACERT.json -u /pb -i myJSON.txt 
 +</code> 
 + 
 +Typically, you can find the JSON files on ''afs'', for example for 2017 data: 
 +<code> 
 +/afs/cern.ch/cms/CAF/CMSCOMM/COMM_DQM/certification/Collisions17/13TeV/Final/Cert_294927-306462_13TeV_PromptReco_Collisions17_JSON.txt 
 +</code> 
 +and for a certain era dataset (''B''-''F''), take a look in: 
 +<code> 
 +/afs/cern.ch/cms/CAF/CMSCOMM/COMM_DQM/certification/Collisions17/13TeV/Era/Prompt/ 
 +</code> 
 +For the recommended JSON files, [[#run_numbers|see below]]. 
 +===== Run numbers ===== 
 + 
 +You can find the correct run numbers and the corresponding JSON files here: 
 +  * [[https://twiki.cern.ch/twiki/bin/viewauth/CMS/PdmV2015Analysis|Run II, 2015 data]] 
 +  * [[https://twiki.cern.ch/twiki/bin/viewauth/CMS/PdmV2016Analysis|Run II, 2016 data]] 
 +  * [[https://twiki.cern.ch/twiki/bin/viewauth/CMS/PdmV2017Analysis|Run II, 2017 data]]
