Detailed Description

Track candidate – seed values and indices.

Author: Christian Höppner (Technische Universität München, original author); Sebastian Neubert (Technische Universität München, original author); Moritz Nadler (maintainer during 2012)

The main task of the TrackCand object is to store a list of indices to cluster objects. Each cluster in the Track is identified by it's detector ID and it's index in the corresponding TClonesArray. Also there is a ordering parameter to order hits. Optionally, plane indices for the hits can be stored (most importantly for fitting with the Daf). This information is used by the RecoHitFactory to automatically load RecoHits into a Track. Through this it is possible to define Tracks over an arbitrary number of different detectors.

In addition TrackCand offers members to store starting values for the fit. The starting values (seeds) for the fit are stored as a 6D state (x,y,z,px,py,pz) and its corresponding 6x6 covariance matrix. All seed getter and setter manipulate these two members but the user can chose using TVector3 or TMatrixD to get/set the seed state. However this information is not automatically used in genfit. But a pointer to a TrackCand can be passed to the a RKTrackRep constructor to make use of this information without manually extracting it from the TrackCand object.
