Legend Codes: Yy = yearly; My =
monthly; Wy = weekly; Dy = daily; X
= XYZ files at 1 minute intervals; and numbers following the code indicate
multiplicity (e.g., Dy4 means daily files with 4 sets of
predictions/day);
Se = SAO elements; MN = maneuver messages; DF
= drag function
Note: On 23 March 2000, the NASA Predictions Center at Honeywell Technology Solutions Inc. (HTSI), formerly AlliedSignal Tecnical Servcies (ATS) transitioned from weekly predictions to daily predictions (reference: SLRmail 0569). In May 2000, MCC stopped producing weekly WESTPAC predictions due to budget constraints.
