sphericalY_deriv

spheroidal.spherical.sphericalY_deriv(s, l, m)

Computes the derivative with respect to theta of the spin-weighted spherical harmonic with spin weight s, degree l, and order m.

Parameters:

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

• l (int) – degree

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

Returns:

spin weighted spherical harmonic function \(\frac{d{}_{s}Y_{lm}(\theta,\phi)}{d\theta}\)

Return type:

function
