How to generate dummy NanoAOD samples
We use self-generated NanoAOD samples for testing, which can be produced with the open source CMSSW framework (see https://github.com/cms-sw/cmssw). The following script generates a file from scratch using fast simulation (see https://twiki.cern.ch/twiki/bin/view/CMSPublic/SWGuideFastSimulationExamples).
The used files are hosted in the repository https://github.com/KIT-CMS/CROWNTestingSamples.
It should be noted that these files must be used solely for testing purposes and do not contain any useful information for physics analysis.
