Starting to work on this

It seems that there is an effect that 'randomly' assigns the x position of a hit to 0 at the end. This is an effect and not real as this neither appears in the truth hits nor in the hits for reconstruction before the reco starts. After the 3D matching this effect is there. I'll trace this through and fix it

I think I managed to solve the issue. See branch 120-...

AsaNehm commented 2 weeks ago

Forgot to fix the 'random' hits in the middle of tracks. Now taken care of by handling two hits per plane in the matching step correctly

Will be merged into the main branch with PR 122
