IauOrientationParameters Class

A structure containing the orientation data computed at a particular time. The data represent the direction of the pole of rotation and the rotation about that pole.

Properties

	Name	Description
	Declination	Gets the declination of the north pole of the body with respect to the International Celestial Reference Frame, in radians.
	RightAscension	Gets the right ascension of the north pole of the body with respect to the International Celestial Reference Frame, in radians.
	Rotation	Gets the rotation about the north pole used to align a set of axes with the meridian defined by the IAU report, in radians.
	RotationRate	Gets the instantaneous rotation rate about the north pole, in radians per second.

Methods

	Name	Description
	Equals(IauOrientationParameters)	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).)
	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.)
	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.

Remarks

These values correspond to what is released by the IAU/IAG Working Group on Cartographic Coordinates and Rotational Elements, with two notable exceptions: the values are in radians as opposed to degrees, and the analytical models are computed in terrestrial time as opposed to barycentric dynamical time.
