10.4 Some computer-aided duplication checks are carried out in Phase II, in part by STScI and also by observers who wish to check whether any of their own observations are being duplicated. Any duplications found that were not justified explicitly in the Phase I proposal and recommended by the review panels or the TAC will be disallowed. No compensatory observing time will be allowed and the observing time will be removed from the allocation.
