TrackCand dip treatment where Theta > 90° [message #8312]

Hi all,

since the _dip member of a TrackCand usually stores the cosine of the dip angle relative to the xy-plane, this parameter is only unambiguous for tracks where Theta relative to the z-axis is less than 90°.
I.e., using only the information from the TrackCand, I can't get the correct parameters of tracks which have a Theta > 90°. How can I properly treat such tracks?

Best regards,

Marius
