| Abstract: |
The USNO CCD Astrograph Catalog South (UCAC-S) project is a high precision astrometric survey of the entire southern hemisphere for the 7-16 magnitude range, aiming at an accuracy of 20 mas for 8-14m stars. A 4k x 4k CCD is used at the back-end of a 5-element, 0.2 meter aperture astrograph. A 2-fold overlap pattern of 43,839 fields will produce 1.8 terabytes of compressed raw data, stored on tapes and CD-ROMs. The project started in January 1998 at CTIO and is scheduled for 2 years to complete. Customized Fortran routines are used throughout. The data structure, quality control procedures and software layout are described. |
