MESSENGER MAG Time-Averaged Calibrated RTN Coordinates Science Data Collection

The spacecraft postion is given by the radial distance from Sun center, northward latitude above the instantaneous ecliptic plane, and azimuth angle of the spacecraft in the instantaneous ecliptic plane with respect to the Earth-Sun line, positive in direction of the Earth's orbital motion. The data are tagged with latency corrected UTC and MET time stamps at the center of each interval.

The RTN RDR is derived from the Science CDR for this coordinate system with time averages computed within 1, 5, 10, and 60 s intervals.
