Method Detail

• getLocation

  int getLocation()

  The location of the track state. Location can be set to: TrackState::AtIP, TrackState::AtFirstHit, TrackState::AtLastHit, TrackState::AtCalorimeter, TrackState::AtVertex, TrackState::AtOther

• getD0

  float getD0()

  Impact paramter of the track in (r-phi).

• getPhi

  float getPhi()

  Phi of the track at the reference point.

  See Also:

  getReferencePoint

• getOmega

  float getOmega()

  Omega is the signed curvature of the track in [1/mm]. The sign is that of the particle's charge.

• getZ0

  float getZ0()

  Impact paramter of the track in (r-z).

• getTanLambda

  float getTanLambda()

  Lambda is the dip angle of the track in r-z at the reference point.

  See Also:

  getReferencePoint

• getCovMatrix

  float[] getCovMatrix()

  Covariance matrix of the track parameters. Stored as lower triangle matrix where the order of parameters is: d0, phi, omega, z0, tan(lambda). So we have cov(d0,d0), cov( phi, d0 ), cov( phi, phi), ...

• getReferencePoint

  float[] getReferencePoint()

  Reference point of the track parameters, e.g. the origin at the IP, or the position of the first/last hits or the entry point into the calorimeter.
