    Yes, JPL.

     
     'delta      deldot' =
       Apparent range ("delta", light-time aberrated) and range-rate ("delta-dot")
    of the target center relative to the observer. A positive "deldot" means the
    target center is moving away from the observer, negative indicates movement
    toward the observer.  Units: AU and KM/S
     
     '1-way_down_LT' =
       1-way down-leg light-time from target center to observer. The elapsed time
    since light (observed at print-time) would have left or reflected off a point
    at the center of the target. Units: MINUTES
