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

218 APPENDIX E. BAT SOFTWARE REVISION HISTORY
All unit tests pass, and are based on the "production" version of the
BAT CALDB, as released to the public.
2. Summary of tool changes
New tools
batwarpimg
* New task which adjusts a BAT image for known non-linear image distortion
* For source detection, batcelldetect should be used instead of this task
Revised tools
batbinevt
* Bug fix to the way the final time bin was written, in some rare cases.
* Bug fix to transfer the MJDREF* keywords properly, when combining GTIs
* Bug fix to remove buffer overflow error tickled by the new parameter library
* Primary HDU images are now labeled with HDUNAME instead of EXTNAME.
This is still compatible with standard CFITSIO and DS9.
* New time binning algorithm, MATCHLC, which allows the time binning
of an existing light curve to be cloned.
* Write NULL values in bins that have zero exposure (when minfracexp is 0)
* Slight changes to error messages
batcelldetect
* Bug fix: clustering of >2 sources during the PSF fit stage was done
improperly, and is now fixed
* Bug fix: known bright sources which touch the border of the image were being
improperly detected as new sources
* New feature: adds distortion correction to position reporting
(the distortion map is pointed to by the ’distfile’ which defaults to CALDB)
* Internal changes of the use of the WCS library
* Primary HDU images are now labeled with HDUNAME instead of EXTNAME.
This is still compatible with standard CFITSIO and DS9.
* Catalog I/O is more forgiving if TUNIT/TNULL values are not present
batfftimage
* Primary HDU images are now labeled with HDUNAME instead of EXTNAME.
This is still compatible with standard CFITSIO and DS9.
batmaskwtevt
* New feature: adds distortion correction to position calculation
(the distortion map is pointed to by the ’distfile’ which defaults to CALDB)
batmaskwtimg
