ClassicalEquationOfEquinoxes Class

Represents the classical equation of the equinox as defined in the Explanatory Supplement to the Astronomical Almanac. This equation has been in use for many decades. For the updated equation of equinoxes defined by the IERS in 1996, see IersTechnicalNote21. To apply this equation of equinoxes, replace the existing EquationOfEquinoxes with an instance of this class.

This class uses the existing NutationModel and PrecessionModel.

The ClassicalEquationOfEquinoxes type exposes the following members.

Constructors
  NameDescription
Public methodClassicalEquationOfEquinoxes
Initializes a new instance.

Properties
  NameDescription
Public propertyIsFrozen
Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an ObjectFrozenException will be thrown if an attempt is made to do so.
(Inherited from DefinitionalObject.)
Top
Methods
  NameDescription
Public methodClone
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).)
Public methodEnumerateDependencies
Enumerates the dependencies of this object by calling EnumerateT(T) for each object that this object directly depends upon. Derived classes which contain additional dependencies MUST override this method, call the base implementation, and enumerate dependencies introduced by the derived class.
(Inherited from DefinitionalObject.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Public methodFreeze
Freezes this object. Further attempts to modify it will result in an ObjectFrozenException.
(Inherited from DefinitionalObject.)
Public methodGetDefinitionHashCode
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)
Public methodGetEquationOfTheEquinoxesEvaluator
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.

(Inherited from EquationOfEquinoxes.)
Public methodGetEquationOfTheEquinoxesEvaluator(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.

(Overrides EquationOfEquinoxesGetEquationOfTheEquinoxesEvaluator(EvaluatorGroup).)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodIsSameDefinition
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
