Plan: - Running load JUL1700A, near the end of the load. Observing PG 1404+226
        with ACIS-S/HETG (obsid 812). Retract HETG during maneuver between
        obsid 812 and 729 (KES 73).

NOTES/ISSUES/PROBLEMS 
--------------------- 

1) The HETG was retracted on a time basis starting at 205:210400. The
   time to retract was 155.03 secs as computed from real time telemetry,
   exactly as specified in the load. We went manually to format 4 at 205:2050,
   after stop science for 812. Format 2 was commanded by the load at
   205:210649. 

   Paul Plucinsky noted that some science data (3 min) would be lost
   due to the manual format switch.

   The starting and ending positions for HETG were
