(IASF - INAF Roma) 1. Introduction ● The SuperAGILE (SA) instrument is a X-ray detector for Astrophysics measurements, part of the Italian AGILE satellite for X-Ray and Gamma-Ray Astronomy. Launched on 23/04/2007 from India, SuperAGILE is now studying the sky in the 18 - 60 KeV energy band and can detect sources with advanced imaging and timing capabilities and good spectral capabilities. 2. Fixed & transient sources detection ● The instrument has entered its full science productivity after having ended Science Verification Phase (SVP), lasted from July 2007 to November 2007. ● Several astrophysical sources has been detected and localized, including Crab, Vela X-1 and GX 301-2. We can confirm at the moment that the instrument has the skill to resolve correctly sources in a field of view of [- 45, +45] degrees interval, with the angular resolution of 6 arcmin, and a spectral analysis with the resolution of 8 keV. Transient events has been also detected, with confirmation from other observatories (see [1]). Transient sources can be detected by SA with the aid of its temporal resolution (2 microseconds) and using signals coincidence on different portions of the instrument. Fig 4.

The Data Processing System Data transmitted to Malindi Ground Station (Kenya) are forwarded to Telespazio Control Centre (Fucino, Italy) and then to INAF institutes and to the ASDC Data Centre (Frascati, Italy). During the SVP INAF institutes are using but also testing and improving the data processing system that will then be consolidated at ASDC at the end of the SVP. The SA data processing scientific software performing at the AGILE Ground Segment is divided in modules, grouped in a processing pipeline named SASOA. The processing steps are: ● data reduction; ● photonlist building; ● sources extraction; ● single source refined analysis. It provides electronic noise filtering, attitude correction and background subtraction, a quick and easy web-based access to the data reports the state of the detector and the detected sky signals (see figures 1-5).
