pyseobnr.eob.dynamics.initial_conditions_aligned_ecc_opt.compute_IC_ecc_opt(*, m_1: float, m_2: float, chi_1: float, chi_2: float, eccentricity: float, rel_anomaly: float, H: Hamiltonian, RR: RadiationReactionForceEcc, params: EOBParams) → tuple[float, float, float][source]

Compute the initial conditions for an aligned-spin eccentric BBH.

Parameters:

  • m_1 (float) – Mass of the primary

  • m_2 (float) – Mass of the secondary

  • chi_1 (float) – z-component of the dimensionless spin vector of the primary

  • chi_2 (float) – z-component of the dimensionless spin vector of the secondary

  • eccentricity (float) – Desired initial eccentricity

  • rel_anomaly (float) – Desired relativistic anomaly

  • H (Hamiltonian) – The Hamiltonian object to use

  • RR (RadiationReactionForceEcc) – The RR force to use

  • params (EOBParams) – EOB parameters of the system

Returns:

Initial values of (r, pphi, pr)

Return type:

tuple
