CLAIRE : secondary requirements

SR1  Coarse pointing

SR2  Fine pointing

(1)     the focal length is the distance between the middle of the lens frame to the front of the detector surface

(2)     the attitude restitution depends on several factors :
         - alignment star sensor-lens optical axis with respect to gamma ray axis
         - misalignment between the optical axis and the gamma ray axis
         - resolution angle of the finder telescope
         - data analysis
         - etc....

(3)     Desirable to be as large as FOV of startracker, so any star found can be brought to center of FOV
         Worst case = total field of view of detector.
