en in correctly identifying the arguments to this function:
          &#952; &#160; is taken as the polar (colatitudinal) coordinate with &#952; &#160; in [0, &#960;], and &#966; &#160; as
          the azimuthal (longitudinal) coordinate with &#966; &#160; in [0,2&#960;). This is the convention
          used in Physics, and matches the definition used by <a href="http://documents.wolfram.com/mathematica/functions/SphericalHarmonicY" target="_top">Mathematica
