Reports access information for each strand access interval for a Chain consisting of just two objects. The time intervals are sorted using the start time of each strand access interval. The azimuth and elevation angles are reported with respect to a frame determined by the first object. The azimuth angle is the angle from the X axis (positive about the Z-axis) to the projection of the apparent relative position vector into the XY plane. The elevation is the angle of the apparent relative position vector from the XY plane, with positive angles being used when the vector has a negative Z component. When the first object is a Facility, Place, or Target, the XYZ frame is Topocentric (X aligned with North, Y aligned with East, and Z aligned with the detic nadir of the detic subpoint of the first object with respect to its central body). When the first object is a Satellite, Missile, or LaunchVehicle, the XYZ frame is CbiVVLH (inertial vehicle velocity local horizontal frame, with the Z axis aligned with the anti-radial direction and the X axis constrained toward the inertial velocity direction). When the first object is an Aircraft, GroundVehicle, or Ship, the XYZ frame is CbfVVLH (fixed vehicle velocity local horizontal frame, with the Z axis aligned with the anti-radial direction and the X axis constrained toward the central body fixed velocity direction) when the central body fixed velocity is not close to zero; when the velocity is close to zero, then the Topocentric frame is used. When the first object is a Sensor, then the frame is determined by its parent object as described above.
