Different data stream, coming from different trigger chain, for different purpose
  • Express stream
  • Physics_main
  • B physics stream
  • Zero Bias, etc..
When a data taking run is over(typically 8 hours):

Bulk rec uses majority of tier0 resources.

  • AOD: Analysis Object Data, physics output like electrons, muons, tracks, etc.
  • HIST: Histograms for monitoring.
  • ESD: Event Summary Data, contained detailed reconstruction output like calorimeter cells and tracking hits (not produced for physics_main)
  • DRAW/DESD: for selected events.

Calibration Loop over express stream:

  • Histograms to monitor.
  • Alignment work of inner tracker can be done.
  • The beamspot is determined (with new alignment).
Calibration loop (48hrs)

Defects and GRL: take Muon DQ as an example: MyMuonDQTutorial. Good quality of data, 'quality' measured by subdetector performance.
