  3. 1. SAO/HEASARC Coordination • HEASARC established partnership with SAO in 1999 in order to strengthen the ties between the two groups, access expertise of both groups, maximize common approaches, and allow integration of the Chandra archive • Steve Murray assumed HEASARC Associate Director role • Funding for ~1.25 FTE provided to support closer ties in the areas of archive standards, CalDB and software development (e.g., DS9) • Partnership has been effective with coordinated extensions to archive standards, CalDB and providing direct support for DS9 development • Steve Murray stepped down as HEASARC AD Feb 2004 to concentrate on new responsibilities and Roger Brissenden assumed PI role • Roger’s role as HEAD AD and CXC Manager provides an opportunity for even closer ties with the CXC, and maximizes resource leverage • Effort during the present 4 years focused on full Chandra archive integration, extending CalDB, support for DS9 and VO, with an opportunity to locate the Chandra archive at SAO for the long term Roger Brissenden

  5. 2. Feb ‘04 HUG Issues (a) Long term plan for the Chandra Archive • Plan to establish the Chandra permanent archive at SAO as part of the HEASARC included in proposal to Senior Review • Approach ensures data remain co-located with expertise (b) Chandra Data Archive Plans • CXC data archive formats are HEASARC/OGIP FITS compatible • CXC uses the CalDB format and is working actively to extend standard Roger Brissenden

  6. 3. Chandra Mission Status • 7 years of Operation on 23 July 2006 • Cycle 7 observations on track, observing efficiency close to optimal • Spacecraft and Science Instruments continue to operate well; no significant anomalies • NASA funding baseline for 10 year mission; planning for 15+ • Consumables not a factor in extending lifetime Roger Brissenden

  7. 4. HEASARC Activities at SAO • Goals Presented to Senior Review • Full Chandra Data Archive (CDA) integration with the HEASARC to provide complete access to Chandra archive metadata through the multi-mission search and retrieval software. Allows for Chandra Archive at SAO/HEASARC long term. • Upgrade to CalDB and CalDB tools to allow more effective support for current and future missions. • SAOImage ds9 maintenance, ports and as resources allow, selected new functionality. Roger Brissenden

  8. 5. Chandra Data Archive (CDA) • Current volume: • 2.85 TB in 10.65 million files (currently growing faster during reprocessing run) • Essential data at second server at CfA • Active mirror sites (public primary and secondary data products only) • LEDAS, UK (2000) • ASDC, Rome, Italy (2004) • HEASARC (2005) • IUCAA, Pune, India (2005) Roger Brissenden

  9. CDA: Holdings Roger Brissenden

  10. CDA: Observations • Distributed over the course of the mission: • 4751 proprietary observations • Publicly available: • 4079 Scientific observations • 1399 Calibration observations Roger Brissenden

  11. CDA: Downloads Roger Brissenden

  12. CDA: Downloads Roger Brissenden

  13. CDA: HEASARC Integration • 2003: The CDA integrated in HEASARC Browse – i.e., Chandra looks like other missions at the HEASARC website • 2005: The CDA mirror at HEASARC fully integrated in HEASARC Browse – i.e., Chandra data access identical to other missions at the HEASARC website Roger Brissenden

  14. CDA Plans: FITS Dictionary • Comprehensive dictionary of all keywords used in Chandra data products • User query interface from CDA web page • Status: awaiting completion of keyword descriptions (2006) Roger Brissenden

  15. CDA Plans: Bibliography • Complete through 2005 • 6891 articles, of which 4038 refereed • 6299 data–literature references: • 1685 papers • 2978 distinct observations • Categories: • 2920 Present specific observations • 2949 Refer to published results (including multi-wavelength, follow-up analysis, theory to explain Chandra data) • 417 Instrumentation, software, operations • 206 Predict Chandra results • 329 Cannot be classified • User access: • Chaser • Dedicated CDA interface • ADS Roger Brissenden

  16. CDA: Bibliography Package • Available as multi-mission tool (2006) • Contains: • Configurable database • Mission-specific flags and lists, database links • Associated literature keywords • Literature – dataset links • Maintenance interface • Automatic ADS mission-specific keyword search of abstract and body • GUI for processing candidate papers, including categorization, flag assignment, access to paper • Provided to XMM GOF Roger Brissenden

  17. 6. CalDB Chandra Metrics: • 13 CalDB upgrades • 126 new files added • 10 new codename types • ~158 old files retired • Current CalDB index includes 814 paired files and extensions. Roger Brissenden

  18. CalDB: HEASARC Tasks • Adapting CalDB to mission-independent tool design: coord. with Mike Corcoran • Automate setting of CalDB file selection parameters (2006-7) • Higher-level processing of archival data • Ensure calibration version consistency with the calibration history of input data (2007) • CalDB system for new missions and software architecture • Improve data structure extensibility (2008) Roger Brissenden

  19. 7. SAOImage ds9 • Current version 4.0b9 (released today) • Supported on 9 hardware platforms • Last Year • 3 Incremental beta releases • over 30,000 downloads • In addition to HEASARC supported missions, collaborating with ground based: • DEIMOS, GEMINI, MMT Roger Brissenden

  20. ds9: New Features • Catalogs • Load / Save / Filter / Sort • Supports VizieR (CDS) catalog servers • Regions • Composite Regions • Templates • Instrument Field of View • New Optional GUI Configurations Roger Brissenden

  21. ds9: Current Development • New Infrastructure • Pure Tcl/Tk implementation • New Windows version • New MacOSX Aqua version • Internationalization Roger Brissenden

  22. Catalog Support • Full support for loading, displaying, sorting, filtering, and saving catalogs • Example shows overlays of the HST and GSC catalogs Roger Brissenden
