[time-nuts] Cheap Rubidium (heatpipe cooling for)

[Bob Camp]

Hi

The answer would appear to be that before they ovenize the physics package it's the more important one. In a real unit I'm guessing that over the time interval of interest it's going to vary from unit to unit. For very tau inside 10 seconds on the LPRO the answer looks like it's the electronics.
