Documentation for getting started with DUNE ND Common Analysis Format (CAF) files produced by ND_CAFMaker.

Start here

1. What is a CAF? Why CAFs?: high-level overview of the CAF format and what it is (and is not) meant to hold, in the duneanaobj README.
2. CAF Quick Start: open a CAF, inspect branches, count entries, and make first plots.
3. caf::StandardRecord Doxygen: authoritative C++ reference for the CAF object model.
4. How CAFs Are Organized: one CAF entry per spill, detector-specific reconstructed interactions, and ND-LAr/TMS track matching.

Reference pages

• CAF Glossary: short definitions for common CAF, truth, reconstruction, and indexing terms.
• CAF Production Inputs and Outputs: what GENIE, edep-sim, detector reco, CAFMaker, and CAF files contain.
• Truth Matching Cheat Sheet: how reco objects point to CAF truth interactions and particles.
• Going Upstream from a CAF: what a CAF does not contain, and which upstream file to open for studies a CAF cannot support.

Common questions

• If you have a CAF file and want to make a first plot, start with CAF Quick Start.
• If you are confused about why one CAF entry is not one neutrino interaction, read How CAFs Are Organized.
• If you are trying to understand an index, ID, or abbreviation, check CAF Glossary.
• If a reco-to-truth link looks confusing, use Truth Matching Cheat Sheet.
• If you are unsure whether a study can be done from a CAF alone or needs upstream files, see Going Upstream from a CAF.
