My programme consists of a pre-imaging and a multi-object spectroscopic (MOS) run. What should I submit by the Phse 2 deadline?
You should submit only the pre-imaging OBs. No dummy MOS OBs should be submitted at the general Phase 2 deadline. ESO will make every possible effort to execute all pre-imaging as early as possible, and will release pre-images immediately. In effect all pre-imaging OBs will be treated as ``carry-under OBs'', meaning that they will be executed as soon as they are ready, even if that is before the period starts. For the Phase 2 proposers this means that it is important to submit pre-imaging OBs as soon as possible, even long before the deadline. The earlier valid OBs are submitted, the earlier the pre-images will be taken, and the higher the probability that follow-up MOS observations will be completed within the narrow window of opportunity.
