First Results:the VELA pulsar The picture shows a preliminary count map (Galactic coordinates) of photons with energy above 100 MeV of the Vela Pulsar region. The observation duration is approximately half a day (7 orbits) between May 29 and 30, 2007. This image represents only the central part of the AGILE gamma-ray imager field of view and was built from data with a preliminary background rejection taken with an instrument configuration that is not yet optimized.
