LaunchVehicle: DeckAccess Data: Stop Time CBFVVLH Geometry

The relative geometry at the access stop time, expressed with respect to fixed VVLH axes of the source object.

Name	Dimension	Type	Description
Time	DateFormat	Real Number	Time.
Azimuth	LongitudeUnit	Real Number	Dihedral angle between north vector and velocity vector about the detic nadir vector. The velocity vector is the velocity of the object, as observed in the object's central body fixed coordinate system.
Elevation	AngleUnit	Real Number	Angle between the velocity vector and the local horizontal plane. The velocity vector is the velocity of the object, as observed in the object's central body fixed coordinate system.
Range	DistanceUnit	Real Number	The range (i.e., distance between the primary and secondary object) at the given time.
Range Rate	Rate	Real Number	The rate of change of the magnitude of the relative position vector. This is computed using the analytical formula dot_product(relative_position_vector, relative_velocity_vector) / magnitude(relative_position_vector). This is an exact formula when the velocity is the derivative of position. Some propagators (e.g., SGP4, J2Perturbation, J4Perturbation), however, produce ephemerides where the velocity is not exactly the derivative of position so that this formula does not compute the derivative of range exactly in such cases.
Azimuth Rate	AngleRateUnit	Real Number	The rate of change of the azimuth angle.
Elevation Rate	AngleRateUnit	Real Number	The rate of change of the elevation angle.
Relative Velocity	Rate	Real Number	The magnitude of the difference in the inertial velocities of the primary and secondary objects at the given time.
Horizontal Relative Velocity	Rate	Real Number	The projection of the relative velocity into the horizontal (i.e., XY) plane.
