Presentation Transcript

  1. Monitoring the INTEGRAL satellite • Mathias Beck • INTEGRAL Science Data Centre

  2. The INTEGRAL Mission • The INTErnational Gamma Ray Astrophysics Laboratory (INTEGRAL) is a scientifc mission of the European Space Agency (ESA). • To be launched by a russian Proton rocket on 17-Oct-2002 from Baikonur/Kasachstan.

  3. The Instruments Four Instruments: • Spectrometer (SPI) • Imager (IBIS) • X-ray monitor (JEMX) • Optical monitor (OMC)

  4. The INTEGRAL Ground Segment • Science Operations Centre • Mission Operations Centre • Science Data Centre • Instrument Teams

  5. Science Data Centre • Consortium of a dozen institutes in Europe and the US. • Prime responsibilites: • Detection of Gamma Ray Bursts • Detection of Transient Sources • Provision of 'standard' data products to user community (archive)

  6. Data Processing • Data rate of some 100 kBit/s from the satellite → A few TB of data products over mission lifetime (2-5 years) • Data processed in 'near real-time' as well after consolidation period (10 days) • Data format: Flexible Image Transfer System (FITS) – standard format for astronomy

  7. ROOT @ ISDC • ROOT at ISDC used for • 'high-level' analysis scripts gluing together 'Analysis Executables (ftools) • Interfaced CINT with all support libraries (data I/O, parameter handling, logging etc.) • Interactive Operations Status Monitoring (IOSM) • Intensive use of ROOT graphics classes • Possibility to save and re-load user defined display configurations

  8. Example of IOSM display

  9. More examples

  10. More examples

  11. A last example

  12. Future development • astroroot (see presentation by R. Rohlfs) • Provide non-ISDC specific functionalities to astronomical community • Use of GRID for data analysis for parallel processing on multiple nodes

  13. The End • of my talk is the start for an exciting time for ISDC staff and INTEGRAL users • Launch on October 17, 2002 at 04:41 UT • http://isdc.unige.ch
