Target version:-


In some cases where an event is near or straddles the boundary of the embedded ephemeris in the Ephemeris propagator it attempts to request a time just outside of the bounds and causes an exception.

Hi Hank,

I have reviewed the changes and only have one detail and one change to propose.
The detail is to replace Math.abs with FastMath.abs, to remain consistent
with the rest of the library.
The change is that the DataTransferObject used for serialization should save
and restore the new extrapolationThreshold tield.

Once this is done, +1 to merge the fix and srt the issue as solved.

I think the extrapolated values should still use the interpolation algorithm so the returned velocity and acceleration are continuous across the boundary.
