Based on the scientific evaluation, the TAC will assign a Grade to each of the submitted proposals.
Grade A
will be given to QM proposals having a high score. The observatory will put the highest effort to complete these programs. If not completed, they may be carried-over to the next semester (see Sect. 4.5).

Grade B
will be given to the rest of accepted HSC QM proposals.

Grade C
will be given to the non-accepted proposals, which, however, will get the permission from the TAC to be observed. In this way the TAC will ensure that there are more programs than necessary to fill the time reserved for QM, which gives more flexibility and backup options during observations. Grade C observations will be performed in good or reasonable weather, when there are no A or B targets.

Grade F
will be given to the Filler proposals, i.e. those intended for bad weather (low transparency $<0.5$ and/or seeing $>$1.2"). Filler programs might also be executed during classical nights, if the current classical program has no adequate backup.
When the constraints of a Grade A, B, or C proposal are found to be too severe, they become a subject of “relaxation”, in order to increase the probability of their execution. This may be requested by the TAC, or by SAs during Phase 2, or even during the observing run (see Sect. 3.3).
