Parameters:

  • _arX – array of horizontal position [m]

  • _arXp – array of horizontal relative velocity (trajectory angle) [rad]

  • _arY – array of vertical position [m]

  • _arYp – array of vertical relative velocity (trajectory angle) [rad]

  • _arZ – array of longitudinal positions [m]

  • _arZp – array of longitudinal relative velocity [rad]

  • _arBx – array of horizontal magnetic field component “seen” by particle [T]

  • _arBy – array of vertical magnetic field component “seen” by particle [T]

  • _arBz – array of longitudinal magnetic field component “seen” by particle [T]

  • _np – number of trajectory points

  • _ctStart – start value of independent variable (c*t) for which the trajectory should be (/is) calculated (is constant step enough?)

  • _ctEnd – end value of independent variable (c*t) for which the trajectory should be (/is) calculated (is constant step enough?)

  • _partInitCond – particle type and initial conditions for which the trajectory should be (/is) calculated
