Additional targets

An important policy of the HSC operation, including QM, is the “no additional targets” rule, which means that all targets must be defined at the Phase 1 stage, and (with the exception of very special cases) no new targets will be allowed to include in the program during the OB preparation stage and observations stage.

Some science programs may benefit from proposing more targets than may be possible to observe in the requested time, and defining the final sample after the acceptance and time allocation. During Phase 2 it is also possible to submit list of targets, where the total on-source time exceeds the allocation. Targets within one program can also be prioritized.

Some other restrictions apply to the selection of targets for HSC QM. See the “Clearly Prohibited Cases” in:
