Image processing and astrometric reduction routines of the OCA-DLR Asteroid Survey (O.D.A.S.)

The OCA-DLR Asteroid Survey (O.D.A.S.) is systematically searching for asteroids and comets with special emphasis on Near-Earth Objects, using a 90cm Schmidt telescope and a 2k x 2k CCD camera. The image data are obtained in both stare and scanning mode, and are processed on site with a PC based software package that allows automatic detection of moving objects, provided three images are available of a given area of the sky. In addition we have also developed interactive software to process single frames, both astrometrically and photometrically, which could also be used on archive data. This latter aspect will be presented at the workshop. For more up-to-date information on O.D.A.S. see our webpages at http://earn.dlr.de/odas/odas.htm.
