brilcalc (CMS Luminosity Calculator)

Log in to lxplus.

ssh -Y [email protected]

Set up pip path in lxplus

export PATH=$HOME/.local/bin:/cvmfs/cms-bril.cern.ch/releases/brilconda-3.3.0/bin:$PATH

Do this the first time. Do it also if you want to update the brilcalc version.

pip uninstall brilws
pip install --user brilws==3.8.1

Check your brilcalc version.

brilcalc --version

Get Lumi from Golden JSON file

brilcalc lumi --output-style csv --byls -c web -u /fb -i Cert_Collisions2024_eraC

_Golden.json > 2024C.csv

brilcalc lumi --output-style csv -c web -u /fb --begin 383493 --end 386074 --byls > Lumi2024ByLS.csv

brilcalc lumi --output-style csv -c web -u /fb --begin 383493 --end 386074 > Lumi2024ByRun.csv

Get the 2017 luminosity. Based on the PdmV2017 and on the TwikiLUM TWikis one should use the following.

brilcalc lumi -b "STABLE BEAMS" \
              --normtag /cvmfs/cms-bril.cern.ch/cms-lumi-pog/Normtags/normtag_PHYSICS.json \
              -u /fb \
              -i /afs/cern.ch/cms/CAF/CMSCOMM/COMM_DQM/certification/Collisions17/13TeV/Final/Cert_294927-306462_13TeV_PromptReco_Collisions17_JSON.txt

If you want to get the luminosity by trigger path.

brilcalc lumi -b "STABLE BEAMS" \
              --normtag /cvmfs/cms-bril.cern.ch/cms-lumi-pog/Normtags/normtag_PHYSICS.json \
