Remote: Christopher Backhouse, Katherine Lato, Gleb Sinev, Yun-Tse Tsai, Tracy Usher

Project status report [Gianluca Petrillo]

  • [Bruce Baller] Is there a compendium of prescriptions available? [A] LArSoft will provide a wiki page; document on tracks specifically will be put together later
  • [Lynn Garren] there is also a request for merge from the WireCell crew

Conclusions

  • need a summary of prescriptions

2d -> 3d reconstruction [Christopher Backhouse]

  • [Thomas Junk] Often you have less than 3 N inputs since hits could be merged
  • [Thomas Junk] how do you deal with tracks at different times? [A] it sets all time references (t0) to zero
    • [Tingjun Yang] MicroBooNE just sees track offsets on drift direction, no different from any other tracking algorithm
  • [Herbert Greenlee] how do you deal with ambiguous hits from wrapped wires? [A] the disambiguation is implemented internally to the algorithm
  • [Bruce Baller] how do you deal with x position? is there any accounting of hit width? [A] no hit width is used, hits are considered ideal points in time, and that is converted into x [Tingjun Yang] there is an option in GausHitFinder allowing to split very wide hits
  • [Tracy Usher] how to deal with different response on different planes? [A] it's assuming perfect calibration

Conclusions

  • troubles with BackTracker that Christopher had should be investigated
  • LArSoft should follow up on how to associate energy deposit to 3D points
  • LArSoft will follow up with a name
