◆ pass_prematching()

bool MuonCombined::MuonCombinedTool::pass_prematching	(	const MuonCandidate &	muonCandidate,

private

Use the alignment uncertainty tool to find the last ID measurement and the first MS measurement

One of the two is not found use the old approach as a fallback

The reason is that the IDTrackParticle does not have an associated Trk::Track. That should never happen during reconstruction

Retrieve the position of the ID exit and the MS entrance

Check that both tracklets are actually out of range. That helps us to recover tracks in the endcaps where the MSOE vertex constraint worsens the compability
