The TrkEventPrimitives package

Introduction

The TrkEventPrimitives defines event objects used for tracking that are not defined in the Amg packages GeoPrimitivies or EventPrimitives. All matrix and vector classes are based on the Amg/Eigen.

  • Trk::JacobianCotThetaPtToThetaP his is the 5x5 jacobian for the transformation of track parameters and errors having a momentum representation of (\phi, cot\theta, q/p_{T}) to the new standard representation of (\phi, \theta, q/p) , while the first two variables that express the local position representation keep unchanged.
  • Trk::JacobianThetaPToCotThetaPt This is the 5x5 jacobian for the transformation of track parameters and errors having the new standard momentum representation of (\phi, \theta, q/p) to the representation of ( \phi, cot\theta, q/p_{T}) , while the first two variables that express the local position representation keep unchanged.
  • Trk::JacobianPolarToCartesian is the 5x5 jacobian to guarantee transformation between polar and cartesian coordinates and errors.
  • Trk::JacobianCartesianToPolar is the 5x5 jacobian to guarantee transformation between cartesian and polar coordinates and errors.
  • Trk::JacobianPerigeeToCartesian is the 7x5 jacobian to transform from perigee parameters to cartesian fourmomentum+coordinate vectors and errors.
  • Trk::JacobianCartesianToPerigee is the 5x7 jacobian to transform from cartesian back to 5-dimensional perigee parameters or errors.
  • Trk::JacobianLocalAnglesPhiTheta dummy, needs to be written !
  • Trk::JacobianPhiThetaLocalAngles dummy, needs to be written !
  • Trk::JacobianPxyzToPhiThetaQoverPcartesian is the 3x3 jacobian expressed in cartesian coordinates to transform from cartesian to polar momentum coordinates.
  • Trk::JacobianPxyzToPhiThetaQoverPspherical is the 3x3 jacobian expressed in polar coordinates to transform from cartesian to polar momentum coordinates.
  • Trk::JacobianPhiThetaQoverPToPxyz is the 3x3 jacobian to transform from polar to cartesian momentum coordinates.
