09/06/2003: "HP5065 Offset update"

I just did a check of the offset on a fairly linear piece of data at the end of the run, and came up with an offset of -4.5x10^-12. That's substantially more, and in the opposite direction, than the measurements I made last week. This sample covered only about 12 hours. Because I'm still seeing the diurnal effect, I'm not sure if these measurements are what they should be. I really need to get a comparison against GPS to validate.

In any event, I'm adjusting the frequency up one minor division, to 1.84, and will start a new run with that setting.
