2 SUZAKU HUG 12-13April, 2006 Suzaku Suzaku launched on 10 July X-ray Spectrometer (XRS keV) -X-ray Imaging Spectrometer (XIS keV; 4 units) - Hard X-ray Detector (HXD keV) August : 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 Changes in Mission Phases: now in the extended phase -Suzaku in Senior review in April 2006

3 SUZAKU HUG 12-13April, 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)

4 SUZAKU HUG 12-13April, 2006 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 SUZAKU HUG 12-13April, 2006 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 SUZAKU HUG 12-13April, 2006 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 SUZAKU HUG 12-13April, 2006 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 SUZAKU HUG 12-13April, 2006 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 ) –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 SUZAKU HUG 12-13April, 2006 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
