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
