Project Status Report [Erica Snider]

  • no feedback for LArSoft v6.10 with Geant4 10.2 and and GENIE 2.11.2
  • IFDHC 2.0 supports file search (see Vito Di Benedetto's talk), with a new syntax
  • proposing to deprecate BezierTrack

Conclusions:

  • we do need feedback on new Geant4 and GENIE
  • we also need feeback on the interest for Docker images

CI integration report [Vito Di Benedetto]

  • new DUNE test workflow is being tested
  • IFDHC 2.0 supports file search with ifdh findMatchingFiles instead of ifdh ls

Documentation report [Katherine Lato]

  • still needing more authors to document the algorithms and services they maintain
  • [Herbert Greenlee] automatic redmine e-mails get easily overlooked [A] we write direct e-mails when an issue is put in "feedback" state

Adding optical truth information [Jason Stock]

  • following the model of TPC (SimChannel)
  • LArG4 will be extended
  • a new BackTracker like services
  • [Gianluca Petrillo] this code does not support truth extraction for full simulation [A] That's by design and acceptable; the design does not prevent such a feature from being added at a later time

Kalman fitter project [Giuseppe Cerati]

  • goal: write an optimal Kalman filter to fit a track
  • using MicroBooNE-like self-generated samples, would like to use official ones
  • establishing a reference performance record with three existing tracking algorithms
  • pull distribution for track start direction is a bit too narrow
  • pull distribution for track start position needs to be understood
  • the first version of new fitting algorithm (no pattern recognition) is encouraging

Data product review: phase II [Gianluca Petrillo]

  • [Erica Snider] having no indexing operator will be a potential issue
  • [Thomas Junk] referencing the coordinate names explicitly might make harder to have protoDUNE support with a different drift direction
  • [Thomas Junk] there are instances where time and position are stored in a single TLorentzVector in non-homogeneous coordinates, making silently invalid some of the operations on it; it would be better to have them stored separately

Conclusions:

  • would like to hear comments and concerns about this new library
