Detailed Description

AliHLTTPCCATrackParam class describes the track parametrisation which is used by the AliHLTTPCCATracker slice tracker.

Definition at line 37 of file AliHLTTPCCATrackParam.h.

Member Function Documentation

float AliHLTTPCCATrackParam::SignCosPhi ( ) const
inline

The sign of cos phi is always positive in the slice tracker. Only after coordinate transformation can the sign change to negative.
