Completion Rate of Grade-A and Grade-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 (OB) over the allocated time.
- The "completed" OBs mean the OBs passed the Quality Assessment.
- The most strict one is used if the program set several constraints for different OBs.
- The allocated hours of intensive programs are divided by each semester.
