Twelve localized objects were found during the flight. About half the sky was scanned, and no well known infrared sources were located. Using this to place a lower limit on the minimum detectable power, the scientific team estimated that the objects that were seen, had fluxes (at Earth) 3x10(-12) W/cm2. Each of the objects was seen more than once, at the same celestial coordinates, thus eliminating the chance that these signals were simply noise in the system.
