Alignment code clean up in preperation of dd4hep migration

Wouter Hulsbergen requested to merge cleanupJune2020 into master

The alignment projects needs to migrated to the dd4hep geometry. This is easier if some of the legacy code is removed. Currently, the project contains two alignment algorithms:

  • the original millepede algorithm, with separate implementations for Velo and T-stations
  • the global chi2 algorithm based on the LHCb kalman filter trackfit (Alignment/TAlignment)

The millepede algorithms have essentially not been used since 2011. Since it is not clear who would do the migration, we propose to remove them. The removed packages are:

  • Alignment/VeloAlignment
  • Alignment/AlignmentTools
  • Alignment/MisAligner
