Parameters

zeta
Type: SystemDouble
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.
z
Type: SystemDouble
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.
theta
