void pecsim::correct_dir_newton(double &t_prop, Vec3d &dir, double sf, const Vec3d &x1, const Vec3d &x2, double t_rx, RayTraceConfig config, VecXd &zf, bool debug = false)

Correct the ray tracing result using a Newton method.

Parameters:

  • iter – Current iteration number

  • t_prop – Propagation time in seconds

  • dir – Initial direction vector of the ray (normalized)

  • sf – Path length of the ray (computed by correction)

  • txpos – Function to get the position of the transmitter at time t_tx

  • x2 – Position of the receiver in Cartesian coordinates

  • t_rx – Reception time in seconds since J2000 epoch

  • config – Ray trace configuration

  • zf – Final state vector containing the ray tracing results

  • debug – Debug flag to print additional information
