MuonR4 - Improvements in the segment fit VolI - IV

Johannes Junggeburth requested to merge jojungge/athena:SegmentFixesVolIV into main
  • Reformulate the mathematics of the Mdt segment fit such that |A-B| can be avoided as it would lead to a 1 / |A-B| term in the derivatives and causes several FPEs
  • Started to implement the t0 fit in the Mdt segment seeder
  • Do no longer calibrate the drift circles in the hit -> seed association
  • Unit tests of the underlying distance calculations and derivatives up to second order
