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

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)

Archival Data

• Data sets part of Suzaku archive
• Science housekeeping data organized by
  observation
• gt 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)

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

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
• gt Processing and archive operational in May

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
