Detailed Description

Typedef Documentation

◆ coord2dPair

typedef std::pair< TVector2, TVector2 > coord2dPair

Typedef for the coord2dPair, which represents the DATCONHoughCand.

Hough Tuples.

The coord2dPair consists of the lower left and upper right corner of a Hough Space (sub) sector

Definition at line 32 of file DATCONHoughCand.h.

◆ houghPair

typedef std::pair<VxdID, TVector2> houghPair

Hough Tuples.

Pair containing VxdID ant TVector2 of TODO

Definition at line 71 of file DATCONTrackingModule.h.

◆ svdHitPair

typedef std::pair<VxdID, TVector3> svdHitPair

The DATCON Tracking Module performs track finding / pattern recognition based on SVD hit information.

The SVD hit information undergo a Hough Transformation (HT) and based on the sinoidal curves obtained by this, interceptions of these sinoidal curves are searched in two Hough Spaces (HS), one HS to obtain (r-phi) and (z-theta) information each. The intercept coordinates of the (r-phi) / (z-theta) combinations found are combined in clustering to reduce the number of fake / clone combinations. Afterwards the remaining 2 x 2D information are combined to 3D tracks, assuming the originating vertex of these tracks to be at (x=0, y=0, z=0). These tracks can again be merged and are finally stored as DATCONTracks and as RecoTracks. Tracks found by this module are the input for the DATCONMPHCalculationModule and afterwards for the DATCONROICalculationModule. Useful typedefs for easier data access Pair containing VxdID and corresponding position vector
