pyseobnr.auxiliary.mode_mixing.auxiliary_functions_modemixing.alpha(ell, m, j, h_ellm, h_mm, phi_ellm, phi_mm)

Auxiliary function to obtain the spheroidal mode input values, see Eq.(76) of [SEOBNRv5HM-notes]

Parameters:

• ell (int) – \(\ell\) index of the relevant mode

• m (int) – m index of the relevant mode

• j (float) – dimensionless spin parameter

• h_ellm (float) – amplitude of the (\(\ell,m\)) mode at attachment time

• h_mm (float) – amplitude of the (\(\ell^{\prime} = m,m\)) mode at attachment time

• phi_ellm (float) – phase of the (\(\ell,m\)) mode at attachment time

• phi_mm (float) – phase of the (\(\ell^{\prime} = m,m\)) mode at attachment time

Returns:

the value of alpha

Return type:

float
