Precession Properties |
The Precession type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | MeanObliquity |
Gets the mean obliquity of the ecliptic, in radians.
|
| Theta |
Gets the accumulated precession angle theta, in radians, used to tilt the x-y-plane to the mean equator of date.
|
| Z |
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.
|
| Zeta |
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.
