MinimumBias primary dataset in RECO format from the 7 TeV Commissioning run of 2010 (/MinimumBias/Commissioning10-May19ReReco-v1/RECO)

Description

MinimumBias primary dataset in RECO format from the 7 TeV Commissioning run of 2010. This dataset includes the data from the CASTOR calorimeter, which covers the very forward region in the CMS experiment (-6.6 < eta < -5.2).

The list of validated runs, which must be applied to all analyses, can be found in

CMS list of validated runs Commissioning10-May19ReReco_7TeV.json

Dataset characteristics

System details

How were these data selected?

During the Commissionning run, events were directed to this primary dataset through several different HLT trigger paths, not only through MinimumBias-like triggers.

Data taking / HLT
The configuration files used to assign data to this dataset can be found in the list of HLT configurations (run between 135059 and 135575).

How were these data validated?

During data taking all the runs recorded by CMS are certified as good for physics analysis if all subdetectors, trigger, lumi and physics objects (tracking, electron, muon, photon, jet and MET) show the expected performance. Certification is based first on the offline shifters evaluation and later on the feedback provided by detector and Physics Object Group experts. Based on the above information, which is stored in a specific database called Run Registry, the Data Quality Monitoring group verifies the consistency of the certification and prepares a json file of certified runs to be used for physics analysis. For each reprocessing of the raw data, the above mentioned steps are repeated. For more information see:
