192 APPENDIX E. <strong>BAT</strong> SOFTWARE REVISION HISTORY<br />
Output coordinates now include pixels (IMXPIX,IMYPIX), tangent-plane<br />
coordinates (IMX,IMY), and celestial (RA,DEC). Celestial<br />
coordinates are only produced if the input image has the proper WCS<br />
keywords attached (namely, if an attitude file was supplied to the<br />
batfftimage task). Parameter uncertainties are estimated for<br />
quantities (see _ERR columns). Also, the time, exposure, and other<br />
status parameters are written to the catalog.<br />
An input catalog is accepted (new incatalog parameter). Sources<br />
which are not in the field of view are removed from the catalog when<br />
transferred to the output. Sources which are in the field of view<br />
are retained, and fitted with fixed position during the PSF fitting<br />
stage. Known sources are also excluded from the pixel-detection<br />
stage.<br />
<strong>The</strong> imagemask parameter has been removed, in favor of the pcodefile<br />
and pcodethresh parameters. Now users can supply a partial coding<br />
map, or any map for that matter, and a threshold. Source detection<br />
outside the threshold region will be rejected.<br />
batdph2dpi -- MINOR CHANGES<br />
* Modified batdph2dpi.c to recognize the level_ranges string "1-3,5"<br />
as well as "1-3,5-5". Also called the subroutine headas_parstamp to add<br />
the HISTORY keywords to the dpi file generated.<br />
* Modified par file and code to change "rownumber" to<br />
"rows" and "level_ranges" to "levels"<br />
* Fixed bug that caused program to crash if it was trying<br />
to overwrite an existing file with clobber=no. Also replaced a loop of<br />
calls to fits_read_col by a more efficient single call.<br />
bateconvert -- SIGNIFICANT CHANGES<br />
Added code to perform a quadratic correction to the linear gain conversion<br />
already in the code. If calmode = QUADRATIC, then two new files are read<br />
in: residfile, which contains the residuals between the quadratic and<br />
linear gain fits, and pulserfile, which contains the gain coefficients<br />
between electronic pulser and energy. <strong>The</strong> linear correction is still<br />
performed and the quadratic correction added to it.<br />
batevt2dpi -- MINOR CHANGES<br />
Changed binning expression to correct a bug in the previous script.<br />
batfftimage - CHANGED<br />
<strong>The</strong> tool already accepts and uses the spacecraft attitude file (and
