pyseobnr.auxiliary.mode_mixing.auxiliary_functions_modemixing.mu(m: int, l: int, lp: int, j: float) → float[source]

Equation 11 from [Berti2014] applied to the (2,2), (3,2), (3,3) and (4,3) modes using the appropriate fitting parameters

Parameters:

m (int) – m index of the relevant mode
l (int) – \(\ell\) index of the relevant mode
lp (int) – index of modes with the same m and lp<=l which give rise to mode mixing
j (float) – dimensionless spin parameter

Returns:

the spherical-spheroidal mode mixing coefficient for the specified mode

Return type:

float
