Determining if Vessel's Orbit Has SOI Transition

[stevehead]

I've been writing a plugin that filters out vessels that meet certain criteria. The current code I have is below:

FlightGlobals.Vessels.Where(v => v.vesselType == VesselType.Debris)
                .Where(v => v.orbit.eccentricity < 1.0)
                .Where(v => v.mainBody.atmosphere)
                .Where(v => v.orbit.PeA < v.mainBody.atmosphereDepth)
                .ToList();

Obviously, those with hyperbolic trajectories are already excluded, but I also need to exclude those that have an upcoming SOI transition of any type (e.g. Kerbin -> Mun encounter). Anyone with suggestions on the best way to do this? I see the Orbit class has several attributes that seem relevant to how I would achieve this: activePatch, closestEncounterBody, closestEncounterLevel, closestEncounterPatch, nextPatch, patchEndTransition, patchStartTransition, previousPatch, timeToTransition1, timeToTransition2. I'm just not sure what would be best. Thanks in advanced!

I think the following is what I need to add to the above:

.Where(v => v.orbit.closestEncounterLevel == Orbit.EncounterSolutionLevel.NONE)

If anyone can confirm this is the appropriate solution, please let me know. Thanks!
