Properties
  NameDescription
Public propertyMeanObliquity
Gets the mean obliquity of the ecliptic, in radians.
Public propertyTheta
Gets the accumulated precession angle theta, in radians, used to tilt the x-y-plane to the mean equator of date.
Public propertyZ
Gets the accumulated precession angle z, in radians, used to align the x-axis with the mean equinox of date by rotating along the mean equator of date.
Public propertyZeta
Gets the accumulated precession angle zeta, in radians, used to align the x-axis toward the direction in which the pole is to be tilted off of the ICRF z-axis.

Methods
  NameDescription
Public methodEquals(Object)
Indicates whether another object is exactly equal to this instance.
(Overrides ObjectEquals(Object).)
Public methodEquals(Precession)
Indicates whether another instance of this type is exactly equal to this instance.
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.)
Public methodGetType

Operators
  NameDescription
Public operatorStatic memberEquality
Returns if the two instances are exactly equal.
Public operatorStatic memberInequality
Returns if the two instances are not exactly equal.

Remarks
Precession is represented by three angles: Zeta, Theta, and Z, which compose a rotation in order of Zeta about the third axis, Theta about the second axis, and Z about the third axis.
