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/76X_dataRun2_16Dec2015_v0.db runtime.
76X_dataRun2_16Dec2015_v0 is for the full event range of both for RunC and RunD 2015 collision data.
See further information in the guide to CMS condition database.
For condition data to be used with 2015 CMS simulated datasets see:
Condition data for 2015 CMS proton-proton simulated data at 13 TeV
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.
