L2TracksSTTPT/STTIP/CTT

L2TracksSTTPT, L2TracksSTTIP and L2TracksCTT are three distinct branches in the output ROOT tree. They are TClonesArray's of the same L2Track class (which contains information about a single track) so they contain the same leaves which are filled by very similar methods. The L2TracksSTTPT are sorted by $p_T$, the L2TracksSTTIP by impact parameter and the L2TracksCTT by $p_T$ from the CTT information only.

Accessor	Method used
CTTiPhi0()	cttphi0Bin()	int	azimuthal angle bin number at the DCA point using only the CTT information
CTTiPhiEM3()	cttphiEM3Bin()	int	azimuthal angle bin number at the EM3 layer of the calorimeter using only the CTT information
CTTPt()	cttpt()	float	$p_T$ of a track candidate using only the CTT information
CTTPhi()	from CTTiPhi0()	float	azimuthal angle at DCA
CTTPhiEM3()	from CTTiPhiEM3()	float	azimuthal angle at EM3 layer
CTTSign()	cttsign()	int	charge of the track using only the CTT information()
CTTL2Iso()	cttl2iso()	int	L2 CTT track isolation
CTTIso()	cttiso()	int	L1 CTT track isolation (0: not isolated, 1: isolated)
CTTPreshower()	cttpreshower()	int	L1 CTT track preshower match information (0: no match, 1: loose CPS match, 2: tight CPS match)
STTiPhi()	coarse_phi_bin()	int	azimuthal angle bin number at the DCA point for the track obtained from the final track fit (including STT information)
STTPhi()	from STTiPhi(), FinePhi()	float	azimuthal angle
STTPt()	sttpt()	float	$p_T$ from the final track fit (including STT information)
STTSign()	sign()	int	charge of the track from the final track fit (including STT information)
DEdx()	dedx()	int	dE/dx for the track candidate
Barrel()	barrel()	int	SMT barrel number for the track candidate
Chi2()	chi2()	float	$\chi^2$ of the track fit
FitStatus()	fitstatus()	int	STT status word (0: fit not performed, 1: fit failed to converge, 2: fit successful)
TruncLayers()	trunclayers()	int	more than 58 SMT clusters were associated with the track fitting road. Only the first 58 were considered in the fit
Topology()	topology()	int	the track candidate has 3 layers (1) or 4 layers (0)
SkippedLayer()	skippedlayer()	int	the SMT layer skipped in the fit (valid only if Topology() $=1$)
IPSig()	ipsignificance()	int	significance of the impact parameter calculated by the STT fit
ImpParam()	impactparameter()	int	impact parameter calculated by the STT fit
FinePhi()	fine_phi_bin()	int	finer granularity azimuthal angle at the DCA point: each $\pi$/80 sector is divided into 16 additional bins
TwoPassFit()	twoPassFit()	bool	Track was fitted a single time (false) or twice (true). Used to distinguish cases with a 3 layer track because one detector layer is not active from cases in which a 4 layer fit was possible but gave a bad chi-square
