10.2	Phase II Submission

Successful GO/SNAP proposers must submit a Phase II proposal providing complete details of the proposed observations. Detailed instructions on the preparation of Phase II proposals are provided in the STScI Phase II documentation. Complete observational details must be provided by the Phase II submission deadline. Accurate target coordinates must also be supplied at this time, except for certain Targets of Opportunity or in other exceptional circumstances, provided that those circumstances were described clearly in the Phase I proposal).

Failure to submit a Phase II proposal by the required deadline will result in loss of the time allocation. Program changes after the Phase II deadline are allowed as described in the Policy Document for the Telescope Time Review Board (TTRB), available on the Web.

Proposers are not allowed to make changes to the list of investigators (PI and Co-Is) after acceptance of the Phase I proposal, unless permission is granted by the Head of the Science Policies Group (Claus Leitherer; leitherer@stsci.edu. Requests for this should be well-justified.
