Completion Rate of Grade A and B programs in S19A-S20B semesters
The following figures show the overall completion rate of accepted S19A-S20B Queue-mode programs against the allocated time in hours. Each symbol's color and mark size indicates the seeing size and the moon-phase constraints of each program, respectively. The completion rate is generally related to the seeing, transparency, and moon-phase constraints, as well as the program grade, the target visibility, and the filters.
- The completion rate is the total exposure time of completed Observing Blocks (OBs) over the allocated time.
- The "completed" OBs mean they passed the Quality Assessment.
- The most strict observing constraints are used (i.e., those specified in the original proposal).
- The allocated hours of intensive programs are divided into each semester.
