◆ SelectTrack()

bool V0FinderTask::SelectTrack	(	CbmGlobalTrack *	pTrack,
		int	iTrk )

private

Selects/rejects a track.

Parameters

pTrack	A pointer to global track
iTrk	Global index of the track

Returns: true: Track is selected; false: Track is rejected

Note: Modifies the track, assigning momentum and PID hypothesis

In this function the preliminary selection of tracks is performed. The selection criteria: 1) the track has at least two STS hits for estimation of the PDG codes (pi-, proton, or primary (kaon PDG)) 2) the track has at least one TOF hit for estimation of its momentum 2.1) tracks with the TOF hit times (t - t0) < 0 are rejected 2.2) tracks with the beta > 1 are rejected 3) the track has defined parameters in the first hit NOTE: this cut was used, because the tracks with negative TOF times were not rejected. Now it seems, that the track parameters are always defined.
