*Light generation and particle / light propagation

- Recent developments

• delta-rays in JSirene, non-isotropic light emission profile. Still a sizeable difference between KM3Sim and JSirene.
• output from Gedanken experiments
• Muon scattering implemented
  • note: need for developers (Valentin on KM3Sim)
• Ready to go at production level
  • ORCA6 km3sim/jsirene production like v7.0.1
  • ARCA8 mass production

* comparison between different software

• software is available (JDomino at light level, JPizza at generation level, ...)
  • at generation level, errors can be already thrown
  • at light level, histograms can be expected. not yet at a level where we can

* different PMTs: specific meeting is needed

• homogeneous detector simulation (ORCA) has been run. need to see the results
• we can already run Gedanken experiments
