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

204 APPENDIX E. BAT SOFTWARE REVISION HISTORY
delivery the task has been reworked and tested with real flight data.
batcelldetect, batclean and batfftimage have been significantly
enhanced to operate better with multiple input images.
Both bateconvert and baterebin have a new parameter named
fltpulserfile, which should be the file containing the as-flown
pulser-to-energy conversion coefficients. This file is in CALDB.
Now all unit tests are based on the "production" version of the BAT
caldb.
2. Summary of tool changes
There are no new tools.
Revised tools
batbinevt
* BUG FIX for spectra with zero counts in one of the bins
(energy bins after the zero-bin were being set to NULL)
* BUG FIX for making mask weighted fluxes with DPHs
(the keywords from the input DPH were not being copied)
* BUG FIX for ’infile’ time binning
(the bins were being coalesced)
* Add ebinquant parameter to expose internal energy binning
batcelldetect
* Significant new features regarding processing multiple images in
one invocation.
* New parameter: the ’vectorflux’ parameter determines whether
fluxes are written as a vector in one row, or as a scalar in
multiple rows. For images with different orientations or
exposures, vectorflux must be ’no’.
* New parameter: the ’rows’ parameter determines which images are
processed.
* New parameter: posfitwindow and possyserr relate to systematic
position errors.
* Position fitting is now more robust: newly fitted sources are
fitted with the same number of points as previously known sources.
* Bug fix: now handles the BAT flight catalog as an input catalog.
* The regions listed in regionfile are now different colors depending on
the detection significance.
* Some robustness changes.
batclean:
* No interface changes.
* Modified code so that it now cleans multiple DPIs if the input
file has more than one DPI extension. It will now output multiple
cleaned images, one per output extension and multiple background
