Using L1 Calorimeter Trigger Emulation

Goal of this page

This page contains instructions on using L1 calorimeter trigger emulation. Lists of tags can now be found at SWGuideL1TriggerTags.

Using L1Calo

An example config file, which also runs the GCTMonitor DQM package, can be found at L1Trigger/CMS.GlobalCaloTrigger/test/l1CaloExample.cfg. The DQM output of the job will be found in gctMonitor.root, and the L1 digis in l1CaloExample.root

If you want to include L1 calo digis in your job, add the following to your config file :

include "L1Trigger/CMS.GlobalCaloTrigger/data/L1CaloEmuDigis.cff"

If you also want to convert these to physically meaningful objects (L1Extra), include the following :

include "L1Trigger/CMS.GlobalCaloTrigger/data/L1ExtraCaloParticles.cff"

The following config file snippet will drop all digis apart from L1 Calo digis :

   module outputEvents = PoolOutputModule
   {
        untracked vstring outputCommands =
        {
            "drop *",
            "keep *_L1GctEmuDigis_*_*",
            "keep *_L1RCTRegionSumsEmCands_*_*",
            "keep *_L1ExtraCaloParticles_*_*",
            "keep *_hcalTriggerPrimitiveDigis_*_*",
            "keep *_ecalTriggerPrimitiveDigis_*_*"
        }
      untracked string fileName = "L1CaloDigis.root"
   }
