  1. OSN Archive: Current status and future implementations José Miguel Ibáñez Instituto de Astrofísica de Andalucía - CSIC Sierra Nevada Observatory First SVO Workshop on data publishing in the Virtual Observatory

  2. Outline • Observatory • Instruments • Data Archive • Architecture • Current status • Future implementations • Conclusions

  3. Observatory • OSN: Observatorio de Sierra Nevada (www.osn.iaa.es) • Observatory located at the ski resort of Sierra Nevada (2896m), Granada (Spain) • Founded in 1981 by IAA-CSIC • Instrument Control Systems developed and maintained by IAA staff • Optics maintained by IAA staff • Remote, In-situ and Service observing • Production: ~20 papers/year

  4. Hard working conditions

  5. Instruments • T150cm • CCD • VersArray 2048B - 2k x 2k • FOV ~ 8’ x 8’ • Filtros: Johnson, Strömgren, Gunn, Molecular, Halpha, Emission, Cometary • Albireo Spectrograph (CCD 2kx2k) • Slit, Argus (IFU) • 5 Diffraction Gratings • Under upgrade (GAIA RVS duplicator)

  6. Instruments (II) • T90cm • CCD • VersArray 2048B - 2k x 2k • FOV ~ 13’ x 13’ • Filtros: Johnson, Strömgren, Gunn, Molecular, Halpha, Emission, Cometary • Strömgren photometer • simultaneous observations of the bands uvby • bands n and w Crawford Hb photo-metric system

  7. Instruments (III) – to be archived • T60cm • BOOTES-IR (under development) – GRBs alerts • T35cm • CCD Kodak 4008 x 2672 • FOV ~30’ x 20’

  8. Data Archive - www.osn.iaa.es

  9. Data Archive Architecture • Lector • Automatically retrieve FITS files from the instruments (daily) • Parse headers • FITS renamed YYYYMMDD.HHMMSS.<filaname>.fit • Insert data into BD • User subscription and notification • Generate report • GUI • Web interface • Queries and data download (public & proprietary) • Image & header preview

  10. Architecture

  11. E-R Database

  12. ADA project • ADA (Archivo de Datos Astronómico) • Funded by project P07-FQM2864 of Junta de Andalucía • Started March 2008 • First release: Sep 2009 • Raw data (science & calibrations) • Collaboration with company

  13. Main functionalities • Raw data (science & calibrations) • Easy to add new instruments  Edit XML config file • Automatic user subscription  OBSERVER keyword • Public & Proprietary data • Proprietary period: • Metadata (headers): used defined, default to 1.5 year • Data (images): used defined, default to 1.5 year • Name Resolver (Sesame service) • Outputs: html, csv, VOTable • Download: Tarball

  14. Development tools • Linux OS: Debian 5 • MySQL DB • Apache Tomcat 6 • GUI: Spring Framework v2.5.6 + jQuery 1.3.x

  15. Computer system • 2 x CPU Xeon E5430 @2.66 GHz (2 x 4 cores) • 16 GB RAM • 5 TiB RAID 5+1 • Linux Debian 5.05 • @ IAA • Radio-link OSN-IAA

  16. Web interface: query

  17. Web interface: results

  18. Current status: numbers • 60 users • 2013: 210 GB / 68k files • Total: 786 GB / 260k files)

  19. Future developments • Update OS: migration to Debian 7 • Add Strömgren data (photometric tables)  convert to FITS • Improvements to Web interface • Query optimization • Improvement of user data search (by campaign ID) • Improvement of file download process (dataset > 3000 files) • Astrometric calibration (WCS): Astrometry.net • VO services data publication • ConeSearch • SIAP (Simple Image Access Protocol) • SSAP (Simple Spectrum Access Protocol)

  20. Future++ developments • Make available to the community observations taken before September 2009 (2002-2009): CD/DVDs ingestion • Reduced data  Pipelines • Spectra • Image • Photometric catalogs High level data products VO
