[time-nuts] new paper on Allan Variance errors

[Jeffrey Pawlan]

The latest IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency
Control  (May 2007) has a very important paper by Dawkins, McFerran, and Luiten
"Considerations on the Measurement of the Stability of Oscillators with
Frequency Counters"

Many of us use or have used a high resolution reciprocal counter to measure
short term stability of a source. This paper shows that the result is often off
by 33% and can be off by more than an order of magnitude, depending on the
amount of frequency and phase noise in the DUT.
