The EarthOrientationParametersData type exposes the following members.

Constructors

	Name	Description
	EarthOrientationParametersData(JulianDate, Double, Double, Double)	Initializes a new instance with the specified parameters.
	EarthOrientationParametersData(JulianDate, Double, Double, Double, Double, Double, Double, Double, Double, Double)	Initializes a new instance with the specified parameters.

Properties

	Name	Description
	CelestialPoleOffsetX	Gets the x-offset to the definition of the Celestial Intermediate Pole (CIP), in arc seconds.
	CelestialPoleOffsetY	Gets the y-offset to the definition of the Celestial Intermediate Pole (CIP), in arc seconds.
	Date	Gets the instant at which the parameters are specified, in the TAI time standard.
	DeltaEpsilonCorrection	Gets the correction to the nutation in the obliquity of the ecliptic (delta Delta epsilon) with respect to the IAU1980 theory, in arc seconds.
	DeltaPsiCorrection	Gets the correction to the nutation in longitude (delta Delta psi) with respect to the IAU1980 theory, in arc seconds.
	LengthOfDayCorrection	Gets the correction to the length of a solar day ("LOD"), in seconds. This defines the difference between the astronomically determined length of a day and the length of a standard solar day (86400.0 SI Seconds). This accounts for effects from zonal tides, oceanic tides, angular momentum transfer from the moon, and other effects on the Earth's rotation.
	PoleWanderX	Gets the pole wander in the X direction at this instant, in arc seconds.
	PoleWanderY	Gets the pole wander in the Y direction at this instant, in arc seconds.
	SecondsDifference	Gets the number of seconds difference between Date in UTC and TAI.
	TaiOffsetFromUtc	Gets the number of leap seconds ("DAT") as specified in the EOP file. This yields the relationship between the UTC and TAI time scales by the following relation: DAT = TAI - UTC
	Ut1MinusUtc	Gets the difference UT1 - UTC at this instant.

Methods

	Name	Description
	Equals(EarthOrientationParametersData)	Indicates whether another instance of this type is exactly equal to this instance.
	Equals(Object)	Indicates whether another object is exactly equal to this instance. (Overrides ObjectEquals(Object).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns a hash code for this instance, which is suitable for use in hashing algorithms and data structures like a hash table. (Overrides ObjectGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Operators

	Name	Description
	Equality	Returns if the two instances are exactly equal.
	Inequality	Returns if the two instances are not exactly equal.
