CMS collaboration
Environment Condition CMS CERN-LHC
Condition database includes non-event-related information (Alignment, Calibration, Temperature, etc.) and parameters for simulation/reconstruction/analysis software.
These files are needed when running a CMSSW job on the open data environment (VM or container), and they are available in the /cvmfs/cms-opendata-conddb.cern.ch file system. They are automatically read from /cvmfs/cms-opendata-conddb.cern.ch/80X_mcRun2_asymptotic_2016_TrancheIV_v8.db runtime.
80X_mcRun2_asymptotic_2016_TrancheIV_v8 is to be used with the 2016 simulated data released for data science studies.
See further information in the guide to CMS condition database.
If you are using the CMS Virtual Machine image or the CMS container image environments, then the condition data files will be served automatically from /cvmfs/cms-opendata-conddb.cern.ch/
or from a file server at runtime, and therefore you do not need to download these files. If you need to have them locally, you can download them from here.

Neither the experiment(s) ( CMS ) nor CERN endorse any works, scientific or otherwise, produced using these data.
