PrecessionModelGetEvaluator Method (EvaluatorGroup)

Gets an evaluator to evaluate the precession at given dates.

The result of evaluating will be a Motion<Precession> which represents the precession angles and may also provide their derivatives. To check whether a particular PrecessionModel provides precession rates, see the Order property on the result returned from the evaluator.

abstract GetEvaluator : 
        group : EvaluatorGroup -> MotionEvaluator<Precession>

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: MotionEvaluatorPrecession
The evaluator.
