Preliminary Results of the EUVE Slew Survey: Aug 1993 - Feb 2000

NASA's Extreme Ultraviolet Explorer (EUVE) spacecraft operates in low-earth orbit and consists of four telescopes -- three imaging "scanners" and the deep survey imager/spectrograph -- and covers bandpasses from about 70-760 Angstroms. Throughout the mission, EUVE has collected data while operating in different modes, from the All-Sky Survey when the spacecraft spun about its long axis at 0.2 degrees per second and captured data with the scanners, to inertially pointed observations when the spacecraft looks at specific astronomical targets using the deep survey imager/spectrograph. In addition, science data was often collected while the spacecraft was slewing from one pointed observation to the next, which has yielded a random "Slew Survey" of the sky with the imaging scanners and the deep survey instrument. We will discuss the EUVE Slew Survey data set, processing techniques, and potential problems associated with instrumental responses. We will also present preliminary skymaps and a list of possible EUVE sources detected. This work was funded through NASA/UCB Cooperative Agreement NCC5-138.
