Function Documentation

VecXd pecsim::ray_derivative(double s, const VecXd &z, double t_epoch_tx, RayTraceConfig config, VecXd &store_vec, bool use_precomputed_vals, bool debug = false)

Compute the derivative of the ray at a given point.

Parameters:

• s – Path length at the point

• z – State vector containing position, direction, time, and TEC

• t_epoch_tx – Transmission epoch in seconds since J2000

• config – Ray trace configuration

• store_vec – n (1) and grad_n (3) storage

• debug – Debug flag to print additional information

Returns:

Derivative of the ray at the given point
