This was a relic of a time when we were comparing KF-based and ST-based alignments. It is not needed anymore and we should remove this cut so we can use all tracks found by KF, including ones that may have only one sensor from a given module.
Still To Do
[ ] Check that this does not break previous alignment studies
[ ] Maybe see if it helps?
[ ] Maybe change the meaning of the nhit cut as described in #944
