Compute the initial value of the radial momentum, including dissipative contributions. One can use a PN formula or a resummed formula (default).
- Parameters:
r0 (float) – Starting separation
pphi0 (float) – Starting angular momentum
dot_r_cons (float) – Time derivative of r computed using the conservative dynamics
dot_r_diss_ecc (float) – Time derivative of r computed using post-adiabatic corrections
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
omega_avg (float) – Orbit-averaged orbital frequency
eccentricity (float) – Desired initial eccentricity
rel_anomaly (float) – Desired relativistic anomaly
H (Hamiltonian) – The Hamiltonian to use (an instance of Hamiltonian class)
RR (RadiationReactionForceEcc) – Function that returns the RR force with eccentric corrections
params (EOBParams) – EOB parameters of the system
- Returns:
The initial radial momentum in tortoise coordinates
- Return type:
[float]
