Quadrature Weights
Solving for Spherical Harmonic Analysis Quadrature Weights
In “More Notes on Calculating the Spherical Harmonics”, I used a simple iterative approach to converge on relatively accurate analysis of coefficients from a pixelized image on the sphere. In this article, we will look at the other method to improve the accuracy of approximating integration with finite sums by including so-called quadrature weight factors.
