An Overview of the Digitized Astronomy Supernovae Search Control and Image Processing Software
A 75-cm telescope has been automated with a Prime 300 minicomputer to search approximately 250 galaxies per hour for premaxima supernovae. The telescope operates completely automatically and without a human operator. The computer handles all aspects of the search including startup and shutdown, weather monitoring, object scheduling, and the generation of a report of each night’s activity. The control software consists of five interacting processes executing in a time-sharing environment. Fields are compared to reference fields with a high speed algorithm which compares object lists instead of subtracting complete images. All image processing is performed in real-time as the search proceeds. In February 1987, the Digitized Astronomy Supernovae Search (DASS) system began full operation.
