Sean (or anybody else),

I was chatting with Eric from Kinemetrics to try and figure out what
kind of specsmanship they are using to get so much dynamic range from
their accelerometer.

He said that they use something called a "half octave" for the bandwidth
(bandwidth being a necessary component of any noise spec of course) and
that this was published in the literature and some sort of a standard.

To save me looking all over, can you tell me what a "half octave" is?

I was also surprised to hear that they used something called a "noise
model" which is supposed to be the median noise of production sensors,
which of course means that half the sensors they ship don't meet the
spec.  Is this "noise model" thing legit?
