Detailed Description

track candidate object.

The purpose of the track candidate is three folded:

• provide the generic MuPatCandidateBase interface for tracks
• keep track of segments used to build track
• cache additional information that cannot be stored on the track

The following information is cached:

• the stage during the pattern recognition the candidate was made (Moore legacy)
• the pointer to the track
• a vector of the segments that were used to form the track
• a vector of the segments that were already tested against the candidate but failed. This information can be used to speed up the pat-rec code by avoiding fits that were already tried.
