Write clearly and simply. Please remember that the TAC is small and that all members grade all proposals. Therefore, while it is possible that there is a TAC member with expertise in your field, your proposal will be read and graded by many non-experts. It is essential that you present the scientific motivation for your proposal in language that astronomers outside your field can easily understand.
Separate requests should be submitted for each distinct program. Unnecessary proliferation of proposals, however, is discouraged. A single proposal can request time on more than one telescope. Because of different levels of oversubscription or TAC judgment on the relative merits, it can occur that some runs are scheduled while others are not. There is no reason to split related observing into multiple proposals on the theory that the whole proposal will rise or fall on the basis of the most competitive telescope.
Please follow the rules. Using incorrect forms or omitting required information is not acceptable. Handwritten proposals are not permitted.
