Properties
  NameDescription
Public propertyCelestialPoleOffsetX
Gets the x-offset to the definition of the Celestial Intermediate Pole (CIP), in arc seconds.
Public propertyCelestialPoleOffsetY
Gets the y-offset to the definition of the Celestial Intermediate Pole (CIP), in arc seconds.
Public propertyDate
Gets the instant at which the parameters are specified, in the TAI time standard.
Public propertyDeltaEpsilonCorrection
Gets the correction to the nutation in the obliquity of the ecliptic (delta Delta epsilon) with respect to the IAU1980 theory, in arc seconds.
Public propertyDeltaPsiCorrection
Gets the correction to the nutation in longitude (delta Delta psi) with respect to the IAU1980 theory, in arc seconds.
Public propertyLengthOfDayCorrection
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.
Public propertyPoleWanderX
Gets the pole wander in the X direction at this instant, in arc seconds.
Public propertyPoleWanderY
Gets the pole wander in the Y direction at this instant, in arc seconds.
Public propertySecondsDifference
Gets the number of seconds difference between Date in UTC and TAI.
Public propertyTaiOffsetFromUtc
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
Public propertyUt1MinusUtc
Gets the difference UT1 - UTC at this instant.

Methods
  NameDescription
Public methodEquals(Object)
Indicates whether another object is exactly equal to this instance.
(Overrides ObjectEquals(Object).)
Public methodEquals(EarthOrientationParametersData)
Indicates whether another instance of this type is exactly equal to this instance.
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Returns a hash code for this instance, which is suitable for use in hashing algorithms and data structures like a hash table.
(Overrides ObjectGetHashCode.)

Gets the Type of the current instance.
(Inherited from Object.)
