  1. Suzaku archive Lorella Angelini/HEASARC

  2. Suzaku • Suzaku launched on 10 July 2005 • X-ray Spectrometer (XRS 0.3-12 keV) • X-ray Imaging Spectrometer (XIS 0.2-12 keV; 4 units) • Hard X-ray Detector (HXD 10-600 keV) • August 10 2005 : loss of the XRS usability • Observing program changes : • New SWG program (finalized in Oct 2005) • New AO1 (closing on 6 Jan 2006) (validity April 2006-March 2007) • AO1 results made public on March 16 2006 • Changes in Mission Phases: now in the extended phase • Suzaku in Senior review in April 2006

  3. HEASARC role • Populate and maintain the Suzaku science and calibration data archive • Provide the following services • Public access to the Suzaku archive • Science data analysis software environment • Web server for the Guest Observer Facility • Database system for the Suzaku tables • Long-term archive • MOU and ICD document roles & responsibilities and details the interface between HEASARC and Suzaku GOF Suzaku data archive present at HEASARC and DARTS (ISAS/JAXA)

  4. Archival Data • Data sets part of Suzaku archive • Science & housekeeping data organized by observation => each containing Level 1 (unfiltered) , 2 (filtered), 3 (products) for all instruments for a specific proposal target • Monitoring and/or Trend data organized by type • Calibration data using CALDB infrastructure • File format: • Science, housekeeping and calibration data are provided in FITS format (OGIP standard) • Preview of summary products (e.g. GIF) • HTML used to record processing • Database tables ASCII (TDAT) • To select data via the Web based search facility (BROWSE)

  5. Archive population • Two processing & archive sites : GSFC and ISAS/JAXA • Special Checksum to verify same data output between the processing site • Plan of archive verification between data at HEASARC and DARTS to ensure serving the same data (procedure re-use from Swift) • GSFC processing site sent data & databases to the HEASARC via DTS • Timescale for data and databases • 1 week after an observation is completed (typical observation 1-2 days) • Database tables (suzamastr and suzaxislg) & trend when an update is available (estimated daily) • Archive access via : • HEASARC Web Browse and FTP • Data volume estimated up to 2-3 Gbyte/day

  6. Initial Mission Phase • During the SWG Phase data access to the SWG team • Data encrypted in the archive & key distributed to the Team . • GO data • Data in the archive encrypted & key distributed to the GOs. One year proprietary period. • First public data foreseen ~ 1.5 year into the mission • End of the proprietary period data are decrypted at the archive sites. • HEASARC and DARTS needs to coordinate this operation

  7. Operational plan : status (1) • At HEASARC the hardware configuration is in place: • DTS machine & relevant software (DTS and DAS) • Physical disks in place (total volume 1.3TB) & mounted on the DTS machine and on the FTP area • backup procedure in place (daily and weekly rsync) • Established the DTS label for the different transfers • Data, Database & for the different type of trend data known • DTS data transferring test with processing site (10 Jan 2006) • Database ingest mechanism in place (not tested yet) • Reuse of the Swift software

  8. Operational plane : status (2) • Version 1 processing is under testing . It uses : • The 1st software and CALDB releases to be distributed shortly • Databases : • suzamaster first draft ready for the end2end test • suzaxislog not yet implemented • Distribution mechanism of the encryption key to the US GO to be tested • The first end2end test starts next week (April 17 2006) • Transfer data from the Japan to US processing site • Processing of the data at the US site • Creation of the database at the US site • Data encryption and test the mechanism of encryption key distribution => Processing and archive operational in May

  9. Software and CALDB • HEASARC ingests calibration data in CALDB via the automatic ingest procedure : • Deliveries and updates provided by the GOF • Access via the HEASARC CALDB page dedicated to Suzaku or via FTP or remote access • HEASARC imports the Suzaku software into the HEAsoft package for distribution • Deliveries and updates provided by the Software Team via CVS • Access via the HEASARC software distribution page or via FTP 1st Suzaku software & CALDB releases planned for: 1st week of May

  10. Software Interface • Test software interface docs/software/lheasoft/ astroe2.html

  11. Access via ftp or at heasarc web site /docs/heasarc/caldb/astroe2
