Phase 2 L1 Calo Analyzer

Description

Adapted from: https://github.com/skkwan/phase2-l1Calo-analyzer . This repo is for running the Phase-2 calo emulator. Initial setup follows from: https://twiki.cern.ch/twiki/bin/view/CMSPublic/SWGuideL1TPhase2Instructions , specifically cms-l1t-offline:l1t-phase2-v3.4.44.

Setup (do only once)

cmsrel CMSSW_12_3_0_pre4
cd CMSSW_12_3_0_pre4/src
cmsenv
git cms-init
git cms-merge-topic -u pallabidas:test-pfclusters-CMSSW_12_3_0_pre4
scram b -j 12

Inside L1Trigger directory:

git clone [email protected]:pallabidas/L1CaloPhase2Analyzer.git
scram b -j 12

To run the emulator and create ntuples for the event display, efficiency plots

For running the emulator:

cd L1Trigger/L1CaloTrigger/test/
cmsRun test_Phase2L1CaloEGammaEmulator.py

To call the firmware-based emulator and make an n-tuple for event display:

cd L1Trigger/L1CaloPhase2Analyzer/test/
cmsRun test-l1tEventDisplayGenerator.py   

Use the L1EventDisplay.root file as input inside figures/eventDisplays/plotEventDisplayPhaseIIPFclusters.C. Get plot by running ./makedisplay.sh after suitably changing save location inside the script.

For the efficiency plots:

cd L1Trigger/L1CaloPhase2Analyzer/test/
cmsRun test-analyzer.py

This produces analyzer.root. Use this file as input in figures/efficiencyPlots/makeEfficienciesPlotPF.cpp. Get plots using root -l -b -q makeEfficienciesPlotPF.cpp after suitably changing save location inside the script.
