Class FieldDSSTThirdBodyContext<T extends CalculusFieldElement<T>>


  • public class FieldDSSTThirdBodyContext<T extends CalculusFieldElement<T>>
    extends FieldForceModelContext<T>
    This class is a container for the common "field" parameters used in DSSTThirdBody.

    It performs parameters initialization at each integration step for the third body attraction perturbation.
