There are three main steps to make a sequence:
First, we find the minimum number of orbits necessary to cover the whole asteroid.
Then, we see what happens when you make a plate model using all but ONE of the 5.5 hour time periods.
Finally, for the five-and-a-half hour periods that did not change the plate model significantly when they were removed, we can change the pointing of the camera to get spots we couldn't normally see, or just to improve emission angle.
First, I'll show you the process and sequence for the high mass case (Emily did the low mass case).
