Processing Version 184.108.40.206
Last Updated on 2009 March 24
Notes on V220.127.116.11
The Suzaku software in HEADAS has been updated from Version 7 to 8, and the new calibration files includes a major update for the XRT+XIS effective area calibration, although these changes have little effect on processing.
Software used since v18.104.22.168 includes a critical bug fix for hxdpi. The XIS calibration files in use since v22.214.171.124 include an updated energy resolution calibration for SCI-on data.
The XIS calibration files in use since v126.96.36.199 include an updated energy scale calibration for SCI-on data.
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 events on 2007 July 28.
Major changes in v2.0 are as follows:
- XIS data with SCI-on will be processed
- Empirical correction for the thermal wobbling
- XIS data with P-sum mode will be processed
- The data format of HXD event FITS are changed
- Lower threshold channels of HXD-PIN are revised
- Energy scale calibration of HXD-GSO is revised
- Data screening criteria have been updated
- New "COR2" column is added to the EHK file
- New GTI files for XIS telemetry-unsaturated frames are created
- Timing discrepancy between the XIS (window mode) and PIN is improved
- Calibration status and caveats pages at ISAS.
