[Algorithms] Stupid SH Question

[Dan G. <dan...@gm...>]

Dear List,
  I have a stupid question about Spherical Harmonics.  I am reading your
Peter-Pike Sloan's "Stupid Spherical Harmonics Tricks" (
http://www.ppsloan.org/publications/StupidSH36.pdf).

In the appendix on recurrence rules, he state that P{0,0} is 0, but looking
at the definition for P{m,m} = (1 -
2m)P{m-1,m-1} this would mean that all results are 0.

Shouldn't P{0,0} = 1 instead?

thanks
DanG
