SuperCOSMOS

The main components of SuperCOSMOS consist of a high-precision granite, air-bearing xy table which provides the high accuracy position measurements, a linear CCD array (of 2048 pixels) which provides the high speed scanning capability, and transputers and DEC Alpha workstations for rapid data processing and analysis. The entire system is housed in an environmental chamber operating under class 100 clean room conditions and with strict thermal stability, thereby ensuring integrity of the data during the scan process. SuperCOSMOS has an absolute positional accuracy of  0.25 microns, with a repeatability of better than 0.1 microns (Hambly et al 1998). Both glass plates and films can be accepted for scanning.
