Detailed Description

Track candidate – a list of cluster indices.

Author

Christian Höppner (Technische Universität München, original author)

Sebastian Neubert (Technische Universität München, original author)

The main task of the GFTrackCand 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 rho, to order hits. Optionally, plane indices for the hits can be stored (most importantly for fitting with the GFDaf). 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 GFTrackCand offers members to store starting values for the fit. However this information is not autmatically used in genfit!!! But a pointer to a GFTrackCand can be passed to the RKTrackRep to make use of this information.

Initializing constructor.

Parameters

curv	Curvature from prefit. There is no stringent definition what this parameter means at the moment.
dip	Dip angle from prefit. There is no stringent definition what this parameter means at the moment.
inv	Dummy paramter. Has been used to mark inverted tracks in the past.
detIDs	collection of detector IDs. Each detector ID needs a corresponding GFRecoHitProducer. See RecoHitFactory for details.
hitIDs	collection of hit indices.
