14. T. Courvoisier First results of INTEGRAL 1 The INTEGRAL Science Data Centre (ISDC) Courvoisier et al. A+A in press Link between the data and the community All data (120 kbits/s) are processed at the ISDC: -in real time (few seconds after receipt on the ground) to detect gamma ray bursts and inform the community (IBAS, Merehetti et al. A+A in press) -in near real time (within few hours) to detect new or very variable sources -offline to produce a set of standard products The data are archived and distributed (at present 1.5-2 months after the observation) to the observers Analysis tools are provided to the community http://isdc.unige.ch gives access to the ISDC services

15. T. Courvoisier First results of INTEGRAL 1 The INTEGRAL Science Data Centre Consortium institutes, there is close collaboration with inst. teams ISDC hosted by Geneva Observatory, 35 staff work in Versoix near geneva

16. All data are transferred to ISDC and are analysed there. European Space Operations Center Darmstadt ISDC

17. T. Courvoisier First results of INTEGRAL 1 Observation programme: 30% core programme AO-1 70% open programme AO-1 in progress, AO-2 starts January 1, 2004 Exposure map (ISGRI fully coded FOV) revolutions 1-100

18. T. Courvoisier First results of INTEGRAL 1 Structure of the scans Distribution of scans in the plane Core programme: Galactic plane scans, every 12 days

19. T. Courvoisier First results of INTEGRAL 1 Core programme: Galactic center deep exposure (Ao-2) This is intended to: -monitor and detect compact sources -to map electron-positron annihilation map -to map Aluminium emission

20. T. Courvoisier First results of INTEGRAL 1 INTEGRAL Status: The instruments function very well The observation programme is progressing as expected. The observation efficiency is short of few percent of the optimum The data reach the ISDC in a matter of seconds for near real time analysis The data reach the observers in about 6 weeks -2months.
