A -- RESEARCH AND DEVELOPMENT SOL N66001-98-X-8600 POC Contract Specialist, Ms. Joyce Miller-Corona, Code D212, (619)553-4333. Contracting Officer, Mr. G. E. Brown, (619)553-5725. This modification is issued to the CBD synopsis published on 19 September 1997. The purpose is to publish the following questions and answers in response to BAA N66001-98-X-8600. Question -- Would we still be considered responsive to the BAA if our proposal suggested using the draft specification as goals and supplied a specification which we believe our design will achieve? Answer -- Yes. You would be considered responsive to the solicitation. All proposals that present a sensor concept with design cost and performance trades will be considered responsive and will be reviewed, even if the sensor cannot meet some of the requirements presented in the draft performance specification. Deliverable number 4 that is required from the study asks for an updated "Performance Specification". The purpose of the cost trade study is to show what it will cost to meet the specifications given in the draft performance specification. However, if the sensor concept cannot meet some of the requirements at any cost then the draft performance specification should be updated. Question -- Is there some surface reflectance/emittance you were assuming? Answer -- A standard vegetation reflectance model should be used. For thermal band calculations, temperature of approximately 20C should be assumed. Question -- What date will the proposals be due in order to be considered in the first 30 days? Answer: The due date for the first round is 20 October at 3:00pm local time in San Diego. (0281)
