The true equator mean equinox coordinate system evaluated at the epoch of the object.

Name	Dimension	Type	Description
Time	DateFormat	Real Number	Time.
Z Comp of Ang Mom	Unitless	Real Number	The Z component of the orbit angular momentum vector. This action variable, classically designated as H, is paired with the right ascension of the ascending node angle variable.
Ang Momentum	Unitless	Real Number	The magnitude of the orbit angular momentum vector. This action variable, classically designated as G, is paired with the argument of perigee angle variable.
sqrt(mu * a)	Unitless	Real Number	The sqrt of the product of the gravitational parameter and the semi-major axis. This action variable, classically designated as L, is paired with the mean anomaly angle variable.
RAAN	LongitudeUnit	Real Number	The angle in the XY plane from the X axis to the ascending node, measured in a right-handed sense about the Z axis. in the equatorial plane. For equatorial orbits, the ascending node is defined to be directed along the positive X axis, and thus the value is 0.0. The Calc Object allows a choice of coordinate systems. The default is Earth Centered Inertial.
Arg of Perigee	AngleUnit	Real Number	The angle from the ascending node to the periapsis vector measured in the orbit plane in the direction of the object's motion. The periapsis vector locates the closest point of the orbit. For a circular orbit, the value is defined to be zero (i.e., periapsis at the ascending node).
Mean Anomaly	AngleUnit	Real Number	A measure of the time past periapsis passing, expressed as an angle.
