Detailed Description

Class representing a sequence of three dimensional reconstructed hits.

Member Function Documentation

◆ getEndTrajectory3D()

const CDCTrajectory3D& getEndTrajectory3D ( ) const

inline

Getter for the three dimensional trajectory.

The trajectory should start at the END of the track and follow its direction.

Definition at line 119 of file CDCTrack.h.

       {
         return m_endTrajectory3D;
       }

◆ getHasMatchingSegment()

bool getHasMatchingSegment ( ) const

inline

Get a flag which indicates that the track has a matching segment (probably set in the SegmentTrackCombiner).

This flag can be used for filter decisions (e.g. if the track is fake).

Definition at line 182 of file CDCTrack.h.

◆ getStartTrajectory3D()

const CDCTrajectory3D& getStartTrajectory3D ( ) const

inline

Getter for the two dimensional trajectory.

The trajectory should start at the start of the track and follow its direction.

Definition at line 112 of file CDCTrack.h.

◆ receiveMaskedFlag()

void receiveMaskedFlag ( ) const

Check all contained wire hits if one has the masked flag.

Set the masked flag of this segment in case at least one of the contained wire hits is flagged as masked.

Definition at line 394 of file CDCTrack.cc.

 {
   for (const CDCRecoHit3D& recoHit3D : *this) {
     const CDCWireHit& wireHit = recoHit3D.getWireHit();
     if (wireHit.getAutomatonCell().hasMaskedFlag()) {
       getAutomatonCell().setMaskedFlag();
       return;
     }
   }
 }

◆ setEndTrajectory3D()

void setEndTrajectory3D ( const CDCTrajectory3D & endTrajectory3D )

inline

Setter for the three dimensional trajectory.

The trajectory should start at the END of the track and follow its direction.

Definition at line 105 of file CDCTrack.h.

◆ setStartTrajectory3D()

void setStartTrajectory3D ( const CDCTrajectory3D & startTrajectory3D )

inline

Setter for the two dimensional trajectory.

The trajectory should start at the start of the track and follow its direction.

Definition at line 98 of file CDCTrack.h.

◆ shiftToPositiveArcLengths2D()

void shiftToPositiveArcLengths2D ( bool doForAllTracks = false )

Set all arcLengths to have positive values by shifting them by pi*radius if they are negative.

This can only be done if the radius is not infinity (for example cosmics). The flag can be used to do this for all tracks (default is to do this only for curlers)

Definition at line 423 of file CDCTrack.cc.

◆ splitIntoSegments()

std::vector< CDCSegment3D > splitIntoSegments ( ) const

Splits the track into segments.

Note : No trajectory information is copied

Definition at line 321 of file CDCTrack.cc.

Member Data Documentation

◆ m_qualityIndicator

float m_qualityIndicator = NAN

private

Multivariate classifier output in [0, 1] correlated with probability that track is good match.

Used to reject fakes and clones. Implemented here to be forwarded to RecoTrack.
