Detailed Description

MC-based track finding in the STS.

Author
V.Friese v.fri.nosp@m.ese@.nosp@m.gsi.d.nosp@m.e
Since
2.2.2005
Date
23.10.2016

Ideal track finder in the STS for simulated data. For each MCTrack having at least 3 StsPoints, a StsTrack is created and the corresponding StsHits are attached using the correspondence between StsHit and StsPoint.

Parameters
mHitArrayArray of CbmStsHit
trackArrayArray of CbmStsTrack

@value Number of tracks created

Implements CbmStsTrackFinder.
