[time-nuts] phase/frequency data of real atomic clocks

I have been looking into noise and noise processes in the last couple
of months. Unfortunately, my seemingly simple question how to simulate
power law noise (1/f^a noise) properly led me to a wild goose chase
deep into the mathematical lala-land[1].  

In order to verify that I haven't gone completely off the track,
I would like to check some of the assumptions made with real data.
Hence I would like to ask, whether people here have continuous
phase/frequency data of real atomic clocks, and if I could get
a copy of those, together with a description how it was measured.

I am looking for any kind of atomic clock and any kind of measurement.
The higher the sample rate and the longer the measurement the better,
but I will not be picky. 

If you know someone who has collected such data, any contact
information would also be helpful.

Computer generated data does not work in this case, as I want to
verify that the assumptions made in the mathematical models
have a foundation in the real physical implementations.

Thanks in advance

was difficult, imagine what their offspring "stochastic calculus"
looks like. Now add fractional calculus (half-integrals and
half-differentials, but nothing about fractals per se) to the
whole thing and you get fractals waiting around the corner.

the prosperity and technological sophistication in the world is of no 
use without that foundation.
