Several fixes for sagitta bias corrections in MuonMomentumCorrections

Giacomo Artoni requested to merge gartoni/athena:mmc-iteration-weight into 21.2

This MR includes several bug fixes and improvements in MuonMomentumCorrections related to the sagitta bias corrections part, namely:

  • Inclusion of the SagittaIterWeight property, which allows to control the weight associated to subsequent iterations in the application of sagitta bias corrections (see e70720be).
  • Inclusion of a protection for sagitta bias corrections generating nans for SiliconAssociatedForward muons (see 3f03ad9b).
  • Fixed bug in the propagation of corrected values for ID/MS extrapolated momenta after sagitta bias corrections (see b9637731).
  • Fixed bug in the nominal values for sagitta bias corrections (see 2021f7c6).
  • Moved to using unique_ptr for TProfile2D in sagitta bias corrections as observed in ATLASG-1574 (see a5a0a58a).
