- But the period, and projected semimajor axis, and especially the rate of
- periapsis advance and [beta], are determined from observations using a model.
- They cannot be determined without assuming a particular model. If the
- assumed model includes gravitational waves, you get one value for periapsis
- rate (for example). If it assumes no waves, you get a different result.
- Observations cannot yet say which solution is preferred.

- I, too, will be on travel for the rest of the month. I'll save other
- responses until then. Best wishes. -|Tom|-
