SOFIA Stratospheric Observatory for Infrared Astronomy DCS PDR at RIT3/7/2000 Review Policy SOFIA science support review policy is to facilitate the development of world class instruments. The review policy is guided by past experiences of other ground based and space based facilities. The review board is responsible for making judgments and recommendations concerning the review content. The board chairman is responsible for supervising the review, mediating discussions, meeting the review objectives, and maximizing the value-added contribution of the review board. Following the review, the board meets to discuss findings, review and and assign RFAs, and prepare a draft report. The board rejects of adopts either in part of in-full all submitted RFAs from the review. The chairman prepares a final report of concerns and recommendations. The review board chairman prepared a final report of the review and delivers the report to the observatory directory within two weeks of the review. The final report is distributed to all the meeting attendees by the observatory director following receipt from the board chairman.
