compatibleForTrack()

bool MuonR4::SegmentSelectionTool::compatibleForTrack ( const EventContext &  ctx, const Segment &  segA, const Segment &  segB  ) const

finaloverridevirtual

Segment is on the same spectrometer layer

Segment sector deviates too much

If both segments don't have phi information, then they may be compatible

If one segment has phi information and the other doesn't then just check whether it's possible that the segment with phi is also in the same sector as the other

Both segments have phi information. Ensure that their phi is within 5 degrees

Accept only segments that are 5 degree apart
