harmonic_leaver

spheroidal.leaver.harmonic_leaver(s, ell, m, g, num_terms=None, n_max=100)

Computes the spin-weighted spheroidal harmonic with spin-weight s, degree l, order m, and spheroidicity g using Leaver’s method.

Parameters:

• s (int or half-integer float) – spin weight

• ell (int or half-integer float) – degree

• m (int or half-integer float) – order

• g (complex) – spheroidicity

• num_terms (int) – number of terms in the expansion

• n_max (int) – maximum number of terms in the expansion

Returns:

spin-weighted spheroidal harmonic \({}_{s}S_{lm}(\theta,\phi)\)

Return type:
