Notebook

Using the Open Event Generation Data

The event generation open data is available in the HEPMC2 format, which is a text-based event generator record. Each file of around 10,000 events is compressed to save disk space. The notebook provides a brief introduction to reading the events and making use of them in a variety of ways.
