Hello all,
I just realized a friend published her thesis on phase-noise measurement
on her blog (in german):

You might try a sandwich of rubbery or foamy stuff alternating with
heavy, stiff stuff, like silicon pads/steel plate. And keep air drafts away.
At least that method I am about to try to decouple my geophones during
experiments.

Hello List!
Just got a link to a fresh release from ESA: They dedicate a H MASER at
Estec to steer it with Pulsar measurements from 5 european radio
telescopes and compare it to the adjacent ESA UTC lab, which equipped
with 3 H MASER and 3 Cs clocks.
