     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

              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

          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

     4. HEASARC Activities at SAO
                Goals Presented to Senior Review

   1. 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.

   2. Upgrade to CalDB and CalDB tools to allow more
      effective support for current and future missions.

   3. SAOImage ds9 maintenance, ports and as
      resources allow, selected new functionality.

• 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)
