  1. Tutorial, Leiden August 2008Introduction Gijs Verdoes Kleijn OmegaCEN / Kapteyn Institute Groningen

  2. Astronomical Wide-field Imaging System for Europe • Tutors • Ewout Helmich • John McFarland • Gijs Verdoes Kleijn • Erik Deul

  3. Main objective Astro-WISEA-to-Ω Survey Environment • For astronomical surveys facilitate: • Handling • Calibration • Quality control • Pipelining • User tuned research • Archiving • Disseminating • All collaborators working in same environment: • WHERE EVER they & the hardware+software are • WHAT EVER kind of data and size

  4. The Astro-WISE paradigmTARGET diagram: “raw to redshifts” …and “redshifts to raw”

  5. Classes: Astro-WISE’s building blocks BiasFrame MasterFlatFrame … RawScienceFrame • Classes: building blocks for objects, tasks, recipes • persistency: stored in database • hierarchy • The pros of freedom versus the pros of standards: MOLPvs Surveys ReducedScienceFrame … DATE_OBS make() process_params Creation_date inspect() verify() mymethod() myattribute …()

  6. The Astro-Wise Environment User Python prompt (awe>) Web interfaces • Database • METADATA • Contains ALL input/output Codebase COMPUTE CLUSTERS DATASERVERS

  7. The federated Astro-Wise Environment Leiden

  8. Paradigm in action 1: workflow tracking

  9. Paradigm in action 2: visualizing extreme data lineage

  10. Paradigm in action 3: intelligent processing

  11. What can be ingested into Astro-WISE • Imaging: 15 instruments currently: • Optical: WFI@2.2m, MDM8K@MDM, ACS@HST*, MEGACAM@CFHT, OCAM@VST, SUPRIMECAM@SUBARU, LBCBLUE/RED@LBT, MONICA@WENDELSTEIN, WFC@INT, PDS@ESO • Infrared: WFCAM@UKIRT, ISAAC** • Radio: WENSS@WSRT*, LOFAR@LOFAR** • Tabular data in general

  12. The Astro-WISE paradigmTARGET diagram: “raw to redshifts” …and “redshifts to raw”

  13. What can be created in Astro-WISE….. …and also retrieved (fits/csv/html/png/xml/python pickle …)

  14. Ordering the sea of data 1 • Projects, privileges and context • Data subdivided into projects • Public projects: members are all Astro-WISE users (including anonymous) • Private projects: members are subset of Astro-WISE users • within a project each object has a visibility privilege • only visible for the creator • visible for everyone in the project • visible for whole Astro-WISE • visible for the whole world • visible in the virtual observatory as well • Context= project PLUS public data from all projects

  15. Ordering the sea of data 2 • Default behavior: ‘Newest version is best’ • Calibration timestamps time

  16. Tutorial programme: hands-on • Ultimate goal tutorial • Launch Astro-WISE user community in Leiden • Erik central figure: local Astro-WISE contact

  17. LET’S DO IT
