List of issues/bugs/strange things noticed while working with the CAFs.

Updated for PicoRun4.1 CAFs (2023/10/30)

Common issues

Things noticed in both structured and flat CAFs:

• Repeated G4IDs for primary particles
  • Affected variables: rec.mc.nu.prim.G4ID
• Truth particle type for in common branch always 3 (kSecondary)
  • Affected variables: `rec.common.ixn.dlp.part.dlp.truth.type
• Variables assumed for truth matching only contain values of -1 or 0 (default values according to the SR code)
  • Affected variables: rec.nd.lar.dlp.tracks.truth.{ixn,part,type}
  • Affected variables: rec.nd.lar.dlp.showers.truth.{ixn,part,type}

Flat CAF issues

• Kinetic energy for non-calometric calculation (E_method) always set to -1e-3
  • Affected variables: rec.common.ixn.dlp.part.dlp.E

Structured CAF issues

• Reading anything from the rec.mc.nu branches causes a crash after some number of entries
  • e.g. Reading PicoRun4.1_1E17_RHC.larnd.00000.caf.root will crash at entry 38 using cafTree->Scan("mc.nu.id")

Not necessarily issues

• Empty spills? What causes a spill to be empty?
