Various Scifi tracking improvements and code cleanup

  • Able to define triplet seeds from various layers
  • Allow for the option of selecting more than one triplet per h1 candidate, currently commented out because not throughput performant enough yet
  • Clean up unused constants in LookingForwardConstants.cuh, grouped by LookingForward and LookinForward_sbt
  • Fix in extend missing x layers: include last x layer of T3 now
  • dzdy correction applied now when propagating from Velo/UT to SciFi (implemented by @flpisani )
  • dratio term used for propagation within SciFi, new parametrization for going from Velo/UT to SciFi (implemented by @flpisani )
  • Create functions for propagation within SciFi -> easier to switch between different versions
  • Inline small functions in LookingForwardTools.cuh -> faster, especially those for extrap (propagation within SciFi)

With this MR, we obtain the following efficiencies on 1k BsPhiPhi events, staying at about the same throughput:
