initial_conditions

Module containing functions to compute orbital properties from initial conditions

Functions

constants_from_initial_conditions(a, ...)	Computes the constants of motion \((\mathcal{E},\mathcal{L},\mathcal{Q})\) of the orbit with the given initial conditions.
is_stable(a, initial_position, initial_velocity)	Tests whether the orbit with the given initial conditions is stable
plunging_orbit_initial_phases(a, ...[, ...])	Computes the initial phases \((q_{t_0},q_{r_0},q_{\theta_0},q_{\phi_0})\) of a plunging orbit with the given initial conditions.
stable_orbit_initial_phases(a, ...[, ...])	Computes the initial phases \((q_{t_0},q_{r_0},q_{\theta_0},q_{\phi_0})\) of a stable bound orbit with the given initial conditions.
