Description

ZeroBias primary dataset in AOD format from RunB of 2010

However, the ZeroBias dataset does not contain any validated runs. It is therefore NOT recommended to perform analysis on this dataset. The list of validated runs, which must be applied to all analyses, can be found in

CMS list of validated runs Cert_136033-149442_7TeV_Apr21ReReco_Collisions10_JSON_v2.txt

Dataset characteristics

17192479 events. 138 files. 340.9 GiB in total.

System details

FT_R_42_V10A::All
CMSSW_4_2_8
Recommended container image for analyses is available in the following locations (see guide):
  • docker.io/cmsopendata/cmssw_4_2_8-slc5_amd64_gcc434:latest
  • gitlab-registry.cern.ch/cms-cloud/cmssw-docker-opendata/cmssw_4_2_8-slc5_amd64_gcc434:latest

How were these data selected?

Since the actual ZeroBias triggers were moved to the MinimumBias dataset, the remaining events do not contain useful information and this sample should not be used.

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:
