> Data Process
Suzaku data are distributed as OGIP-standard FITS files,
with calibration already applied (i.e., event files include sky
coordinates and PI channels). Software necessary to apply calibration
to the event data are called "critical FTOOLS" and are
HEAsoft package. Calibration files used by the critical FTOOLS
are available via the HEASARC CALDB
structure, which can be installed on the users' local machines or
accessed remotely. As calibration improves, users will have the
option of applying updated calibration files themselves, or download
the data again at a later date when they have been reprocessed.
Processing Version 220.127.116.11
Last Updated on 2008 June 14
Old versions are summarized in the
Notes on v18.104.22.168
The Suzaku software in Headas is updated from version 6 to 7.
This includes the critical bug fix of hxdpi.
The new XIS calibration files include an updated energy
resolution calibration for SCI-on data.
Notes on v22.214.171.124
The new XIS calibration files include an updated energy scale calibration for SCI-on data.
Notes on v126.96.36.199
The HXD calibration files in use since v188.8.131.52 include an adjustment of the low energy threshold for the PIN, following the onset of the PIN flare event on 2007 July 28.
Notes for v2.X data
In this version, in addition to the newly observed sequences after 2007
June, all the previously processed (v1.x) sequences consisting of SWG, AO-1,
and AO-2 will be reprocessed. If the sequence is proprietary, the PI will
receive an announcement when the new data set is ready. No message
for public sequences, including many of SWG and AO-1 observations whose
proprietary period ended, will be sent out.
Current calibration uncertainties are described in the
"calibration status and caveats".
Major changes in v2.0 are as follows:
