To select all sub-exposures in the visit (if a multi-orbit visit, you can adjust all orbits at one time), you can either manually select each one or select no sub-exposures (which defaults to all sub-exposures). Note that if you select no sub-exposures, and some sub-exposures in the visit are not adjustable, Auto-adjust will only expand those sub-exposures that are adjustable. To select discrete sub-exposures, click on the sub-exposure in the Orbit Planner window or the Tree Editor. To select consecutive sub-exposures, click on the first sub-exposure, then Shift-click on the last sub-exposure desired. To select non-consecutive sub-exposures, click on the first sub-exposure, then Cntl-Click on the others.
In this example, we will select the last 2 sub-exposures in the Orbit 1,
and the middle two pattern points in Orbit 2.
Clicking on the Auto-adjust button will initiate processing, and APT will divide the unused visibility equally among each sub-exposure. Note that changing exposure times can result in changing overheads or buffer dumps, and APT will take these into account when packing your orbits. The results of Auto-adjust show that each sub-exposure in Orbit 1, which were originally 300s long, has now been expanded to 613s. In Orbit 2, the two middle pattern points, which were originally 300s long, have been expanded to 840s; this leaves 369s of unused visibility.
The reason there is so much unused visibility (for Orbit 2) is due to buffer management.
Note that if you did not like the results, you can reset back to the original exposure times by hitting the Clear Actual Durations button. If, in addition, you wanted to also clear the orbit numbers, hit the Clear Orbit Numbers and Actual Durations button.
In this example, we will select no sub-exposures, which results in all
adjustable sub-exposures being used.
After clicking on the Auto-adjust button, we see that all orbits are completely packed.
