Name	Dimension	Type	Description
Time	DateFormat	Real Number	Time.
Mean Semi-major Axis	DistanceUnit	Real Number	Semi-major axis computed from mean elements associated with the specified mean element theory. If the elements associated with the mean theory do not include semi-major axis, it is computed from the elements associated with the mean element theory using normal osculating orbit element conversions.
Mean Eccentricity	Unitless	Real Number	Eccentricity computed from mean elements associated with the specified mean element theory. If the elements associated with the mean theory do not include eccentricity, it is computed from the elements associated with the mean element theory using normal osculating orbit element conversions.
Mean Inclination	AngleUnit	Real Number	Inclination computed from mean elements associated with the specified mean element theory. If the elements associated with the mean theory do not include inclination, it is computed from the elements associated with the mean element theory using normal osculating orbit element conversions.
Mean RAAN	LongitudeUnit	Real Number	Right ascension of the ascending node computed from mean elements associated with the specified mean element theory. If the elements associated with the mean theory do not include RAAN, it is computed from the elements associated with the mean element theory using normal osculating orbit element conversions.
Mean Arg of Perigee	AngleUnit	Real Number	Argument of periapsis computed from mean elements associated with the specified mean element theory. If the elements associated with the mean theory do not include argument of periapsis, it is computed from the elements associated with the mean element theory using normal osculating orbit element conversions.
Mean Mean Anomaly	AngleUnit	Real Number	Mean anomaly computed from mean elements associated with the specified mean element theory. If the elements associated with the mean theory do not include mean Anomaly, it is computed from the elements associated with the mean element theory using normal osculating orbit element conversions.
Mean Nodal Period	TimeUnit	Real Number	Mean nodal period computed based on the mean element rates for the specified mean element theory. Nodal period is defined time between consecutive crossings of the ascending node.
Mean Arg of Latitude	AngleUnit	Real Number	Argument of latitude computed from mean elements associated with the specified mean element theory. If the elements associated with the mean theory do not include argument of latitude, it is computed from the elements associated with the mean element theory using normal osculating orbit element conversions.
Mean Longitude of Perigee	LongitudeUnit	Real Number	Longitude of perigee computed from mean elements associated with the specified mean element theory. If the elements associated with the mean theory do not include longitude of perigee, it is computed from the elements associated with the mean element theory using normal osculating orbit element conversions.
Mean Mean Longitude	LongitudeUnit	Real Number	Mean longitude computed from mean elements associated with the specified mean element theory. If the elements associated with the mean theory do not include mean longitude, it is computed from the elements associated with the mean element theory using normal osculating orbit element conversions.
