Review of notes from last time
- Notes were reviewed
Review of first round of simulation results
- Thomas showed list of plots.
- Much time spent discussion of one plot:
- Sean: geometry could be the cause
- Richard: would like help isolating problem to simulation or to reconstruction
- Thomas will put together a plug-in to explore
- Thomas: both FDC and CDC hits are missing
- question: are truth hits along real track trajectory
- can be explored with event viewer
- Beni volunteers
- This is an issue on GitHub
Other Issues
- Maria Patsyuk reported overlaps in the geometry
- Richard will work on this
- Richard: issues with roll-your-own event generators
- interaction z and t are correlated by machine bunch structure
- decay of long-lived particles can lead to double counting (parent and daughter particles both appear in final state)
- [added in press] Richard wrote new wiki page describing best practices.
- There is a related issue on GitHub
- Sean added an additional plot on the time shift in FCAL showers issue. He sees a difference in hit times vs. shower times.
