  3. Instrument: e-science = share resources beyond workstation • Compute power: • AstroWise grid (RuG, Leiden, MPE, Bonn, INAF) • EGEE-3 • Storage: • AstroWise fileservers (Leiden, RuG, Nijmegen, MPE, Bonn, INAF) • BiG GRID (RuG- NikHef- SARA) • Database: all meta + calibration +source data • AstroWise - Oracle • Application programs + doc’s • Web services • Interoperability: EGEE- EURO-VO

  4. Scattered Archives FIRST ROSAT GAIA 2MASS SDSS

  5. Euro-VO FIRST ROSAT GAIA 2MASS SDSS

  6. ALADIN • Manipulation • X-match • Visualization • Direct links to: CDS Aladin

  7. TOPCAT VOTable view

  8. Large Hadron Collider Tier-0 (CERN): copy of all raw data Tier-1 (~8-10 centers) archive 1/n fraction of raw data & reconstructed data regular re-processing of the raw data archiving data from Tier-2 centers provide central grid services: grid accessible computing and data resources support coordination Tier-2 (~100 centers): data analyses no data archiving LOFAR Tier-0 (RUG): central processor lots of processing, limited archive Tier-1 (~6-8 centers) specialized science analysis advanced processing of (large) data sets dedicated archive, also for Tier-2 centers provide central grid services: grid accessible computing and data resources support coordination Tier-2 (~100 centers): individual scientists data analyses no data archiving Multi-tier models for LHC & LOFAR

  9. AstroWise paradigm

  10. Virtual Survey Telescope • raw pixel data  pipelines/cal files  catalogues • all integrated in one information system • 100% data lineage • 1 dec 2006 delivered! • distributed services • processing GRID Storage GRID • Methods/services GRID NL:Leiden, Nijmegen, Groningen EU: Napoli, Munchen, Bonn, Heidelberg, Paris Santiago

  11. Current Instruments/projects • VST- OmegaCAM • GT, KIDS, VESUVIO, OmegaWhite, OmegaTrans • VISTA • UltraVISTA, VIKING via Edinb. • SuprimeCAM @ Subaru • WFI@2.2m, WFC@ING • ACS@HST Coma legacy survey • Panstarrs • Lofar • Surveys • EoR

  12. Lofar Storage

  13. Astro-Wise VO Properties Benefits integrated dynamic db • on-the fly re-processing • 5LS: 5 Lines Script • All bits are traced • Administration for parallel processing compute GRID SETI@home • Global solutions –astrometry/photometry • Build–in workflow • Fully user tunable – own provided script • Context: projects/surveys, instruments, mydb • Publish directly in EURO-VO
