How were these data selected?
Events stored in this primary dataset were selected because of the presence of low-energy particles (soft-QCD events). This trigger is favourable over the ZeroBias one when the luminosity, and thus the rate of collisions to tape, is too low for ZeroBias to be effective.
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:
Step: RECO
Release: CMSSW_5_3_12_patch1
Global tag: FT_R_53_LV5::All
Configuration file for RECO step reco_2011_MinimumBias

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:
