Implementation of the so-called real spherical harmonics, using the orthonormal normalization, which are related to spherical harmonics as:

$Y_{l0} = Y_l^0 (m=0) \\ Y_{lm} = \frac{1}{\sqrt{2}} \left( Y_l^m + (-1)^m Y_l^{-m} \right) (m>0) \\ Y_{lm} = \frac{1}{i\sqrt{2}} \left( Y_l^{|m|} - (-1)^{|m|} Y_l^{-|m|} \right) (m<0)$

which implies:

$Y_{l0}(\cos\theta,\phi) = N_{l0} P_l^0 (\cos\theta) (m=0) Y_{lm}(\cos\theta,\phi) = \sqrt{2} N_{lm} P_l^m (\cos\theta) cos(|m|\phi) (m>0) Y_{lm}(\cos\theta,\phi) = \sqrt{2} N_{l|m|} P_l^{|m|}(\cos\theta) sin(|m|\phi) (m<0)$

where

$N_{lm} = \sqrt{ \frac{2l+1}{4\pi} \frac{ (l-m)! }{ (l+m)! } }$

Note that the normalization corresponds to the orthonormal case, and thus we have $$\int d\cos\theta d\phi Y_{lm} Y_{l'm'} = \delta_{ll'} \delta{mm'}$$

Note that in addition, this code can also represent the product of two (real) spherical harmonics – it actually uses the fact that $$Y_{00} = \sqrt{\frac{1}{4\pi}}$$ in order to represent a single spherical harmonics by multiplying it by $$\sqrt{4\pi} Y_00$$, as this makes it trivial to compute the analytical integrals, using the orthogonality properties of $$Y_l^m$$...
