  2. T. Courvoisier 1 First results of INTEGRAL

  3. INTEGRAL is an ESA mission with Russian launcher and one US ground station (part time) Instruments provided through national funding. Bus is identical to XMM-Newton T. Courvoisier 1 First results of INTEGRAL

  4. INTEGRAL is on a 3-days orbit with apogee at 150 000 km and perigee at 10 000 km. Maximises time outside the electron belts T. Courvoisier 1 First results of INTEGRAL

  14. 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 T. Courvoisier 1 First results of INTEGRAL

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

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

  17. 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 T. Courvoisier 1 First results of INTEGRAL

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

  19. 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 T. Courvoisier 1 First results of INTEGRAL

  20. 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. T. Courvoisier 1 First results of INTEGRAL

  21. Cygnus X-1 early images ISGRI 15-40 keV SPI T. Courvoisier 1 First results of INTEGRAL

  22. Cygnus X-1 Observations in PV phase (Pottschmidt et al.

  23. Model Fit: Disk+Comptonised component+reflection hump Parameters: KTe = 62keV, τ = 1, reflection: 0.2 similar for all revolutions, in agreement with previous descriptions. Instruments agree very well apart from the normalisations. T. Courvoisier 1 First results of INTEGRAL
