Scientific paper
A description is given of the SAO CCD camera using the 100 x 100 Fairchild chip operated in a direct imaging mode, together with extensive data on its performance in the laboratory and at the telescope. Short descriptions of the cryogenic, electronic, computer control, and optical systems are presented. Laboratory measurements of the correction for the nonuniformity in sensitivity, linearity, system noise, quantum efficiency, and dark current are discussed. Calibrations of the positions and magnitudes of standard stars in clusters and the surface brightness of a standard galaxy are analyzed. These measurements illustrate the effectiveness of the camera as a photometric detector and also calibrate the parameters of the system.
