Suzaku Data Analysis


Analysis of Version 2 Data

  • Things to Watch Out For (Last updated 2013 Aug 16) This frequently update page lists
    • Calibration problems that have recently surfaced
    • Hints on how best to run Suzaku specific software

The version 5.0 of the data reduction guide is now available in HTML, PDF, and PostScript versions. This guide corresponds to Processing Version 2.X data as distributed to US Guest Observers. Although others are welcome to use this guide, there may be differences if data were obtained from ISAS/JAXA, or if the processing version is different.

Users of Version 2 data should update their Suzaku software to Version 6 or newer and also obtain the latest CALDB files.

  • Suzaku FTOOLS Version 20 (Updated 2013 Mar 5)
  • Calibration files and related files can be obtained from the CALDB page at GSFC or from the CALDB page at ISAS.
    • There was a problem with the NXB database in the 20130110 version of XIS CALDB (files ae_xi?_nxb*_20121201.fits). This has been corrected in the 20130305 version (files ae_xi?_nxb*_20130228.fits).
Current calibration uncertainties of Version 2.X data are described in the Calibration status and caveats pages at ISAS.

The non X-ray background files for the analysis of the HXD data can be downloaded from the following locations:

PINGSO
Tuned (smaller systematic uncertainties) Version 2.5 (for observations before 2011-11-031)
or Version 2.6 (for observations after 2011-11-03)
Quick (available sooner than "Tuned") Old Gain (for comparison with old analysis)

1Version 2.6 should be used for observations taken between 2010-03-01 and 2011-11-03 if it has been reprocessed with the latest gsogpt file.

The following pages including information that supplements, or in some cases supercedes, Version 3.2 of the data reduction guide, and have been incorporated into Version 4.0 of the guide.

See also a list of current Suzaku memos - they contain more detailed information of many of the calibration issues.

In publishing results of Suzaku data analysis:
  • Please explicitly list the sequence numbers of the data used. This enables us to cross-link Suzaku data in the HEASARC database and the bibliography in the ADS.
  • How to acknowledge the use of Suzaku data in your publication.


The following pages include information appropriate for v2.x data and software that are also covered in the Reduction Guide, version 3.2.
