Background There exist multi-semester projects in the Taiwanese share of CFHT's observing time. The Taiwanese TAC decides to move to a new evaluation scheme for such long term projects, to simplify the evaluation process, and more importantly, to prevent inconsistent review results from semester to semester on the same project. The New Scheme and Requirement From the semester 2014A, we ask all proposals (including existing ones) that plan to request observing time from multiple semesters to 1. indicate that it is a long-term proposal in the very beginning of the abstract; 2. in the justification, clearly indicate and justify the proposed period of observations; and 3. for ongoing projects, include sufficient description on the progress of the project and publication result (see the next section). When a long term proposal is reviewed for the first time, the TAC will send the proposal to multiple external referees for a thorough review. The referee's comments will have strong influence on the outcome of the time allocation. This applies to all ongoing long term proposal prior to semester 2014A. Once a proposal is approved, its approval status will likely remain in the subsequent semesters but is not guaranteed. The review in the subsequent semesters will emphasize more on the progress of the project, rather than the scientific value and technical feasibility, which should had been evaluated already in the first semester. Programs that fail to make reasonable progress (including publication) will be terminated by the TAC. Competition from other very strong proposals may also lead to a termination, although the TAC do not expect this to happen very often. The Importance of Publication The TAC continuously emphasizes the importance of record of publication in time allocation, especially for old CFHT users and continuing proposals. Long term projects should be particularly honest in listing their publication in the proposal. In the section "Related Publications," we ask continuing long term proposals to list and categorize their papers into: 1. publications that are direct outcome of the CFHT long term project; 2. publications that are based on other past CFHT observations; and 3. publications that are scientifically related but not based on any CFHT data. Proposals that fail to do so may make it difficult for the TAC to judge the progress, and the most serious outcome may be termination of the project. Proposals with Large Time Request The Taiwanese share of CFHT time is roughly 40 hours per semester. Proposals that require comparable or more observing time are highly likely to be split by the TAC into multiple semesters. If the project is not time critical, the TAC suggests the proposers to present it as a long term proposal and comply with the above requirements for long term proposals. The TAC also encourage the proposers of such proposals to collaborate with teams under other CFHT agencies to submit joint proposals.
