The value of the primary (object1) Area times the drag coefficient over the object Mass, expressed in m^2/kg, used for propagation of the primary state vector and covariance to TCA.

The value of the primary (object1) Area times the solar radiation pressure coefficient over the object Mass, expressed in m^2/kg, used for propagation of the primary state vector and covariance to TCA. This parameter is sometimes referred to as AGOM.

The primary (object1) acceleration, expressed in m/s^2, due to in-track thrust used to propagate the primary state vector and covariance to TCA.

Optional ID of the UDL State Vector at TCA of the secondary object. When performing a create, this id will be ignored in favor of the UDL generated id of the stateVector2.

Optional identifier to track a commercial or marketplace transaction executed to produce this data.

Source of the data.

Originating system or organization which produced the data, if different from the source. The origin may be different than the source if the source was a mediating system which forwarded the data on behalf of the origin system. If null, the source may be assumed to be the origin.

Creating agency or owner/operator (may be different than provider who submitted the conjunction message).

Indicator of whether the data is REAL, TEST, EXERCISE, or SIMULATED data:

REAL: Data collected or produced that pertains to real-world objects, events, and analysis.

TEST: Specific datasets used to evaluate compliance with specifications and requirements, and for validating technical, functional, and performance characteristics.

EXERCISE: Data pertaining to a government or military exercise. The data may include both real and simulated data.
