J4PropagatorGetEvaluator Method (EvaluatorGroup)

Gets an evaluator that can propagate at individual dates.

This evaluator propagates the orbit state from InitialConditions at OrbitEpoch based on the GravitationalParameter, J2ZonalHarmonicCoefficient, J4ZonalHarmonicCoefficient, and ReferenceDistance. The result of evaluating will be a Motion<Cartesian> corresponding to the orbital position and velocity at the given JulianDate expressed in the propagator's ReferenceFrame.

	EvaluatorGroup group


Type: AGI.FoundationEvaluatorGroup
The group with which to associate the new evaluator. By grouping evaluators that are often evaluated at the same Julian dates, common computations can be performed only once for the entire group instead of multiple times for each evaluator.

Return Value

Type: MotionEvaluatorCartesian
The evaluator.
ArgumentNullException Thrown when the group is .
