BTag primary dataset in AOD format from RunB of 2011. Run period from run number 175833 to 180252.
This dataset contains all runs from 2011 RunB. The list of validated runs, which must be applied to all analyses, can be found in
Data taking / HLT
The collision data were assigned to different RAW datasets using the following HLT configuration.
Data processing / RECO
This primary AOD dataset was processed from the RAW dataset by the following step (identical to 2011 RunA):
Global tag: FT_R_53_V18::All
Configuration file for RECO step reco_2011_BTag
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:
