The physics package in a CSAC is a vacuum, so it probably won't make 
much difference.

But, as a practical matter, I have a system with a CSAC going through 
thermal vacuum testing as I write this. We'll get some test data and we 
can compare the frequency against GPS and a OCXO at room temp/pressure, 
and at various temps in vacuum.

Remind me in 2 weeks, and I should have the data plotted.
