  1. AVO Prototype & Demos Markus Dolensky, ESO Technical Lead ASTRO-WISE ((G)A)VO Meeting, Groningen, 06-May-2004

  2. AVO Prototype Suite • New and enhanced features: • Aladin for AVO • CDX Cross Matcher • Column Calculator • Data Cubes from CGPS • IDHA Meta Browser • Photo-z on Demand • SED Utility • SIA/SSA Servers • Specview • VOPlot NGC1512 WFPC2 Association Catalog Maoz et al.

  3. Cross-Match Service 2 catalogue planes Data exchange in VOTable UCDs VOTable (2 tables) + thresholds AVO prototype Remote Cross-match Service at CDS VOTable (merged data + distance) New catalogue plane

  4. Column Calculator • Adding computed columns to Vizier tables and custom catalogs • Example below: Compute luminosity distance needed to • derive X-ray flux

  5. Data Cubes from CGPS • Choosing velocity slice from 3D data cube

  6. IDHA Meta Browser • Now also Support for Spectra • http://alinda.u-strasbg.fr/IDHA/lastmodel/

  7. Photo-z on Demand • Complex workflow delivers end user ‚redshifts‘ • Composed of ‚wrapped‘ standard processes • Sextractor (Bertin & Arnouts) - image extraction • Federation tool - VOTable manipulation • Hyperz (Bolzonella et al.) - redshift determination • User selects spatial area of interest: results returned • Four colour ACS data collated • Image classification (in this case z band extraction then dual image mode extraction of the other colours) • Input photometric catalogue generated • Hyperz actioned (compute intensive) • results returned to MySpace in Votable: input to AVO demo • All processes distributed: transparent to end user

  8. Photo-z Workflow ACS data and results are stored on public MySpace Grid Storage Node

  9. SED Utility

  10. SIA/SSA Servers 1. Client issues SSA query Server Selector Dialog • 2. Resulting VOTable is visualized as overlay. Each red line symbolizes one available spectrum in ROI.

  11. Specview New Features: Support for 1d VLT/FORS1+2, ISO LWS+SWS Logging measurements (lines)

  12. VOPlot http://vo.iucaa.ernet.in/~voi/voplot.htm

  13. AVO & IVOA • IVOA Working Group - Applic. to AVO demo • Data Access Layer SIA/SSA servers • Data Model IDHA, SED, 1d spectra • Grid/Web Services WS infrastr., Sesame • Registry registry prototype* • UCD e.g. cross matching • VOTable the exchange format *http://vm06.astrogrid.org:8080/astrogrid-portal/main/mount/registry/registry.html
