21.9: Few updates to SiSpacePointsSeedMaker_ITK:

Noemi Calace requested to merge ncalace/athena:21.9-TestingCuts into 21.9
  • Removing hard-coded value for the maximum radius for seeding
  • Defining the proper cut for the maximum radius for seeding in the configured cuts
  • Tuning one seeding parameter (ported from 20.20... still :( )

Small changes are seen in the statistic tables on 50 ttbar events with pileup (mu=200) for the SiSPSeededSLHCTracks, while no changes are seen on ResolvedSLHCTracks. One small point is that these samples have still the HepMcParticle link problem, so not really reliable for pileup tracks (I guess).
