void TStiKalmanTrackNode::FindCandidateHits

(

const std::set< TStiHit > &

stiHits

)

const

In the provided collection of hits this class method finds all hits within a 5-sigma vicinity around the mean track projection.

The mean track projection is the nominal position of this track node and the sigma is the track projection error.

This method fills an internal container of hit candidates with pointers pointing to the hits found in the original collection. Note that besides the candidate hits the function finds the hit closest to the mean track projection. The hits are selected from the user provided collection 'stiHits' which should normaly be a collection of hits in the parent event to which the track belongs.
