Since

2007

Version

1.0

The class performs track parameters propagation. The track propagation uses TGeoManager for the navigation.

Propagate() [1/2]

LitStatus CbmLitTGeoTrackPropagator::Propagate ( CbmLitTrackParam *  par, litfloat  zOut, int  pdg, std::vector< litfloat > *  F, litfloat *  length  )

virtual

Track parameter propagation.

Parameters

[in,out]	par	Pointer to initial and output track parameters.
[in]	zOut	Z position to propagate to [cm].
[in]	pdg	PDG code of particle.
[out]	F	Output transport matrix. If F == NULL than transport matrix is not calculated.
[out]	length	Length of track segment.

Returns

Propagation status.
