suzaku
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
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
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)
archive population
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
initial mission phase
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
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
operational plane status 2
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

software and caldb
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
