Description
ForwardTriggers primary dataset from the 2.76 TeV Pb-Pb run of 2011.
This is a special dataset with data taken between the fills for noise studies in forward triggers.
Dataset characteristics
409335 events. 361 files. 48.3 GB in total.System details
GR_R_44_V15::AllCMSSW_4_4_7
How were these data selected?
Data taking / HLT
The collision data were assigned to different RAW datasets using the following HLT configuration.
HLT trigger paths
The HLT trigger paths can be studied and selected with the example usage code linked below
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:

How can you use these data?
You can access these data through the CMS Open Data container or the CMS Virtual Machine. See the instructions for setting up one of the two alternative environments and getting started with CMS heavy-ion data data in
