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
• Rogers 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
• 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.

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)

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

14
