Tracker Software Review: Meeting 8¶

November 1, 2017: 1400 GMT¶

Agenda¶

• PR:
  1. AD: Optimize Chi2 cut for “MINUIT” variant
  2. AD, CH: Check and implement MCS errors
  3. AD, KL: Define multi-track requirements
• Track fit:
  1. Investigate whether field integration (e.g. using Runge Kutta) is required to compensate for magnetic field non-uniformity
  2. Make study of magnetic-field alignment with a view to establishing whether the present algorithm is sufficiently insensitive to reasonable assumptions of maximum field-misalignment
  3. Study p-value: split up contributions to p-value shape using MC and study shape in data, e.g. is there an error in the resolution per plane, handling of MCS, handing of energy loss, b field..

1. 50 MeV bump -- more pronounced with MINUIT?
2. CR reports lower downstream efficiency, and fewer events in analysis when using MINUIT -- should MINUIT continue to be the default fitter in MAUS?

3. PR Report: A. Dobbs
4. Track fit Report: C. Hunt

5. Next Steps for review
6. AoB
