leaver_coefficients

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

Computes the coefficients of the Frobenius expansion in equation 18 of (Leaver, 1985)

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) – spheroicity

• num_terms (int, optional) – number of coefficients to compute, automatic by default

• n_max (int, optional) – maximum number of coefficients to compute, defaults to 100

Returns:

normalized array of coefficients

Return type:

numpy.ndarray
