Science Operations Manual (DW) - This manual covers the flight software image scheduling and image processing, the planning tool interface, and other information useful for planning observations.

Calibration and Special Programs

• Thruster Firings (Momentum Dumps) – For the AHEAD momentum dump on DOY 336, below are plots with the time in minutes starting at 336-1500z, followed by thruster counts A1 through A4. Note that the A2 and A3 thrusters are closest to HI, however, A3 rarely fires for a routine momentum dump.Thrusters are fired in bursts on the order of 0.1 sec.

Descriptions in Operations Manual (above). See Table Management and Planning Architecture for explanation of different directories.

Concept of Operations

• SECCHI image scheduling is primarily by relative time schedules

e.g. run schedule yymmddhh.sch starting at 0000 hours UTC. The SECCHI instruments have EEPROM space for many blocks of schedule that can run various lengths of time on board. Additional schedules can be uploaded as needed.

We intend to have schedule blocks that support various types of campaigns. We have some pre-defined schedule blocks in EEPROM in flight.
