E.4. SWIFT BAT SOFTWARE BUILD 6: 2003 AUG 25 195 are now computed, as well as the partial coding fraction if pcodefile is provided. batcelldetect can now output a region file with source positions, compatible with both FV/POW and DS9. In DS9, the source name will be printed next to the marked position. batclean -- SIGNIFICANT CHANGES The tool now cleans sources as well as background. It reads an input catalog as created by batcelldetect to determine the source location in BAT coordinates. It then calls batmaskwtimg, which produces a forward projection of the source onto the focal plane. Also added some additional output options. Added caldb access. batdrmgen -- SIGNIFICANT CHANGES New with this version: 1) The program now accepts many different incident energy bin edges such as LIN, LOG, USER (custom bin edges) and a default (INDEF) spectrum with some of the bin edges adjusted for the Cd and Te K edges. 2) Calibration parameters are now taken from a FITS file where each combination of incident enery, tanx and tany has a corresponding list of parameters that are to be used to generate the correct response. 3) CALDB has been implemented, so if the user types "calfile = caldb" or "depthfile = caldb", the program will use the caldb utility to select the parameter files appropriate for the data to be analysed. 4) The incident energy range upper limit has been increased to 500 keV. 5) Off-axis response has been implemented. 6) Response now includes the escape peaks for Cd and Te in the spectra Limitations of this version: 1) Keywords representing the state of the PHA data (whether or not various corrections have been applied) have not been implemented. 2) The cal parameters file currently has identical entries for each cell - we must change the file to include the right spectral parameters. bateconvert -- MINOR CHANGES Added caldb access for residual and pulser files. Changed the format in which these files are read in. Fixed a bug in the application of the quadratic fit. Added caldb access. batfftimage - CHANGED batfftimage can now read and analyze multiple images in a single run. The images must be in a single file, either as one per image extension, or in a binary table of images. The output file will contain multiple sky images in separate extensions. CALDB access routines have been added (via batutils) to read the aperture and teldef files. Corrections to some coordinate
196 APPENDIX E. BAT SOFTWARE REVISION HISTORY calculations. The keyword for autocollimation correction is now ACOLAPP instead of ACOLCOR. batgse2dpi -- MINOR CHANGES Changed some array allocations to allow compilation on other operating systems. Fixed bug in the code that was improperly indexing the window cut arrays if there were missing rows in the windows lookup table. Now the code reads and uses the block/dm/side/det values in the windows table for indexing. bathotpix - MINOR CHANGES Some changes to support a new library routine for reading images. batid2xy -- MINOR CHANGES Added more functionality to the tool to allow the user to specify detector by DETX/DETY and detector ID as well as Block, DM, Side, Detector. batmasktaglc -- SIGNIFICANT CHANGES Changed much of how the mask weighting is read in and used. Changed the algorithm by which source, background and errors are calculated. Added background column. Generally cleaned up the code. Added caldb access. batmasktagpha -- MINOR CHANGES Added caldb access. Fixed some bugs in the code. batmaskwtimg/evt - CHANGED There a number of new corrections that can be applied in the mask weight calculation: flatfield (combined cosine projection, r-squared, and side illumination effects), pcode (partial coding), ndets (number of detectors), cosine (cosine projection effect only), rsquare (r-squared effects only). The user can also choose unbalanced images (0 to 1) instead of balanced (-1 to 1). The user can choose which direction the weights should apply: backward (default) or forward. ’forward’ creates a mask weight map which most closely resembles the true detector plane image; while ’backward’ is meant for use in mask weighted sums. The detmask parameter has been added, to aid in calculating the ndets correction. CALDB access routines have been added (via batutils) to read the aperture and teldef files.
