EquationOfEquinoxesGetEquationOfTheEquinoxesEvaluator Method (EvaluatorGroup)

Gets an evaluator to compute the equation of the equinoxes.

The result of evaluating will be a Motion<double> which represents the value of the equation of the equinoxes representing the offset between the mean and apparent equinoxes at the given JulianDate. No derivatives are provided.

The equation of the equinox uses a NutationModel and PrecessionModel defined by the instance of EarthCentralBody in the CentralBodiesFacet of the CalculationContext.

Namespace:  AGI.Foundation.Celestial
Assembly:  AGI.Foundation.Models (in AGI.Foundation.Models.dll) Version: 19.1.398.0 (19.1.398.0)
Syntax
public abstract MotionEvaluator<double> GetEquationOfTheEquinoxesEvaluator(
	EvaluatorGroup group
)

Parameters

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: MotionEvaluatorDouble
An evaluator that evaluates the equation of the equinoxes.
