Re: Best Fit Spherical Harmonics


The truncated Fourier fit to a function is also the least-squares fit. I 
have successfully done a spherical harmonic expansion with up to l=5 or 
so with all the associated m's this way. So, just use Fit. As usual with 
this sort of thing, noisy data can mess things up.
