oops, oops, oops,

I missed the boat, or missed the argument.  I think everything
i said was true, but was sort of irrelevant.  (1/f, Mark,
not sky fluctuations!)

So, i should have been asking: is the 1/f noise correlated over
the frequency band?  Harvey says yes?

Harvey:
Yes, according to Bob Fruend, the Power goes like 1/f, so the
rms goes like 1/sqrt(f), making it a VERY SLOWLY decreasing noise
as you switch faster and faster.
