The SWIFT BAT Software Guide Version 6.3 30 ... - HEASARC - Nasa

208 APPENDIX E. BAT SOFTWARE REVISION HISTORY
* Error bars were being underestimated; they are now more correct.
* Added calculation and writing out of GTI extension.
* Added some more keywords indicating what corrections have
been applied (e.g. ndets)
* Fixed the code so that either type of detector mask (image or
table) can be read into the code.
batmaskwtevt
* BUG FIX when events with TIME=0 were at the beginning of the file.
This would cause the slewing/raytracing to choke and not recover.
* BUG FIX regarding the balancing of the mask weights, which would
cause background contamination (esp. at high energies).
* New keywords APERTURE and BTELDEF describe which calibration
files were used to make the image.
* The task now accepts flight-format enable/disable maps.
batmaskwtimg
* BUG FIX regarding the balancing of the mask weights, which would
cause background contamination (esp. at high energies).
* BUG FIX for when user attempts to place the source "behind" the
BAT.
* INTERFACE CHANGE: users should now use the ’infile’ parameter, to
give the task enough information to properly access CALDB.
* New keywords APERTURE and BTELDEF describe which calibration
files were used to make the image.
* The task now accepts flight-format enable/disable maps.
battblocks
* BUG FIX regarding how durations were reported for light curves
with finite bin sizes. The reported durations (and error bars)
should be more robust now.
* Now background GTIs are also written to the ’durfile’ output. The
extension names are GTI_BKG1 and GTI_BKG2.
Tasks batevt2dpi, batgse2dpi, batgse2dph, and batmasktagpha are
considered obsolete, and/or not for end users.
