  1. Quality control of multiwavelength surveys published in the VO Gijs Verdoes Kleijn & Andrey Belikov NOVA/OmegaCEN/Kapteyn Institute Groningen, The Netherlands

  2. To follow up instead of repeating yesterday’s round table discussion… Access to Quality control of opt/ir imaging published in the VO Quality control of multiwavelength surveys published in the VO Gijs Verdoes Kleijn & Andrey Belikov NOVA/OmegaCEN/Kapteyn Institute Groningen, The Netherlands

  3. Examples of current access to quality control performed by creators of publicly available data

  4. Refereed papers • QC information: • Very thorough…potentially • Very un-standardized • Often most important (but fairly high-level)

  5. README.txt • QC information: • Thorough nitty-gritty details • Very un-standardized • Close to data itself

  6. On-line data repositories • QC information: • Linking data exploration→ QC • Very un-standardized

  7. Access to QC info via VO • Uniformize way of access (also look&feel) • Link from data to already available QC info wherever possible • Standardize only the easy standardizable (small) fraction • Description (“metadata) is zero order quality info • Description data itself • Description data derivation

  8. In VOExplorer/Astroscope

  9. In Aladin ?

  10. In VO registry ?

  11. Access to QC info via VO • Uniformize way of access • Link from data to already available QC info wherever possible • Standardize only the standardizable (small) fraction • Description (“metadata) is zero order quality info • Description data itself • Description data derivation

  12. An example of public access to description of • DATA • DATA DERIVATION • QC

  13. A single but federated environment to calibrate, archive and disseminate astronomical imaging Brazil

  14. Extreme backward chaining

  15. Extreme backward chaining • Astro-WISE stores: • Data descriptionData derivation description • Publicly available for public data

  16. Extreme backward chaining This also publicly available for public data …..idem for next slides

  17. Quality View : bundling QC parameters from database

  18. Quality View cont.

  19. Quality View cont.

  20. Quality View cont

  21. Astro-WISE publishes to VO

  22. From Aladin to QualityWISEwork in progress….‏

  23. From Aladin to Quality-WISE

  24. Conclusions • 0th order Quality Control =description data+its derivation • Astro-WISE links description data & its derivation & its QC to the VO • Want to know more about Astro-WISE? • http://www.astro-wise.org • www.astro-wise.org/Public/published_versionEN65_astrowise_only.pdf • www.astro-wise.org/Public/2007ASPC..376..491V.pdf
