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.

Track finding algorithm This just reads MC truth (MCTracks and MCPoints), creates one StsTrack for each MCTrack and attaches the hits according to the MCTrack of the corresponding MCPoint
