lib.theory.gaussian_covariance.legendre_product_integral(ells, range=(- 1, 1), norm=False)

Return integral of product of Legendre polynomials.

Parameters

• ells (int, list, tuple) – Order(s) of Legendre polynomials to multiply together.

• range (tuple, default=(-1,1)) – \(\mu\)-integration range.

• norm (bool, default=False) – Whether to normalize integral by the \(\mu\)-integration range.

Returns

toret – Integral of product of Legendre polynomials.
