Eric, Yes, the manual was the first place I looked; that's what I was talking about with "...Blackman-Nuttall is also mentioned in the operations manual..."
I misnamed the document "operations manual" instead of "operating manual." Sorry for the confusion over the name.

I'm not sure whether the actual formulas are there or whether it related the names to the official methods. If you can't find what you're looking for, let me know and we can dig it out of the source.
