Hi Danny, Since this doc is going to be used frequently for reference, it might be good to define everything once and for all and leave nothing for the obvious. That way there will be much less of a need to re-figure any of these things out. With this motivation, here are my comments:
* In equation 3, N is not defined. What is the origin of or citation for 2 and N-1 in this equation? * In equation 3, what is R(V)? Is it real(V)? Then why does the LHS mention imag? * Citations or source for equations 6 and 7 will make this very self-contained * What is meant by 1D and 3D Raleigh-Jeans law? Not sure if it is standard terminology.

Please circulate and let me know if you catch any errors or want a number updated.
