Each chart is drawn to represent a specific time. How is this time chosen?
First, we determine all of the times that the visit can be scheduled. We choose one of those scheduling opportunities and determine the exact start time of the visit at the chosen scheduling opportunity. We then draw each target in the visit at the start time of the visit unless the target’s solar system target windows cannot be satisfied at the start of the visit. In that case, we draw the target at the start of its first solar system target window after the start of the visit. The times shown in the charts are not necessarily the times at which the observations will actually execute. Confirmation charts are intended to verify the geometric constraints before scheduling so that problems may be caught and corrected before scheduling. The times shown in the charts are times when the target’s geometric constraints can be satisfied. They are not times from an actual schedule. If we waited to make the charts after the visit was scheduled, we could show the exact time for each target; but i
