pyseobnr.eob.fits.fits_Hamiltonian.dSO(nu, ap, am)[source]

Fit for the spin-orbit calibration coefficient dSO at 4.5 PN

See Eq(91) in [SEOBNRv5HM-notes] .

Parameters:

nu (float) – reduced mass ratio.
ap (float) – symmetric spin combination ap = m1*chi1 + m2*chi2.
am (float) – antisymmetric spin combination ap = m1*chi1 - m2*chi2.

Returns:

The value of dSO.

Return type:

float
