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

E.12. SWIFT BAT SOFTWARE BUILD 14: 2005 MAR 22 209
daria CVS server.
All unit tests are based on the "production" version of the BAT caldb.
2. Summary of tool changes
There is one new tool, batupdatephakw. From the documentation:
: batupdatephakw updates the BAT ray tracing columns in a mask weighted
: spectrum. This is important especially for gamma-ray bursts or other
: events where the spacecraft has slewed. Without the update, the
: keywords will reflect the ray tracing status at the end of the
: event data set, which will lead to an erroneous detector response
: matrix.
This task was implemented in response to the known BAT science
analysis issue, entitled, "batmaskwtevt: Slewing Raytracing Keywords
Wrong".
Revised tools
batbinevt
* Correct name of POISSERR keyword in output spectra
* INTERFACE CHANGE: Allow the user to delete bins with zero counts.
Before, the task always deleted these bins, in order to prevent
battblocks from crashing. (’delzeroes’ parameter)
* Some warning messages for unlikely user configs.
batcelldetect
* INTERFACE CHANGE: New parameter ’hduclasses’ which allows
filtering of input images by HDUCLASn keywords.
* Now able to read an image without an auxiliary tangent plane
coordinate system.
* Input catalog can have galactic coordinates (if the image is
also in galactic coordinates)
* Output images now have proper HDUCLASn keywords
batclean
* Can now enter custom background models via the ’bkgmodel’
parameter.
* INTERFACE CHANGE: Can now rebalance the focal plane image before
or after cleaning, with various rebalancing options (’balance’ and
’balancefirst’ parameters).
* INTERFACE CHANGE: Can now ignore certain sources in the catalog
via the ’ignore’ parameter.
* Fixes and simplifications to the way the background model is
applied.
* New CLEANLEV output keyword keeps track of the generation level of
cleaning.
