D.8. <strong>BAT</strong>FFTIMAGE 141<br />
(time = 0) [real ]<br />
Command line override for the image time. This MET time is used to interpolate the attitude<br />
file. By default the image midpoint time is used (= (TSTART+TSTOP)/2).<br />
(maskwtswgain = 0.03) [real ]<br />
Mask weight technique software gain correction factor. When corrections=maskwt, the image<br />
is divided by (1+maskwtswgain). This is correction is software algorithm dependent and not<br />
intended to be changed by the user.<br />
(copyall = YES) [boolean ]<br />
If set, then batfftimage will copy any extra HDUs to the output file. If not set, then only<br />
the sky images are written. Extra extensions are any HDUs that come after the image<br />
extension(s).<br />
(clobber = NO) [boolean ]<br />
If the output file already exists, then setting “clobber = yes” will cause it to be overwritten.<br />
(chatter = 2) [integer, 0 - 5 ]<br />
Controls the amount of informative text written to standard output. Setting chatter = 1<br />
produces a basic summary of the task actions; chatter = 2 (default) additionally prints a<br />
summary of input parameters; chatter = 5 prints debugging information.<br />
(history = YES) [boolean ]<br />
If history = YES, then a set of HISTORY keywords will be written to the header of the<br />
specified HDU in the output file to record the value of all the task parameters that were used<br />
to produce the output file.<br />
D.8.5 EXAMPLES<br />
1. Reconstructs the sky image from the detector plane image focalplane.img. <strong>The</strong> aperture map,<br />
aperture.img, is in the current directory.<br />
batfftimage focalplane.img skyimage.img<br />
2. Make a partial coding map for the given detector configuration given in detmask.img. <strong>The</strong><br />
output file is the image pcodemap.img. If the detmask parameter were not given, then a default<br />
one would be used, which assumed that all detectors were enabled.<br />
batfftimage NONE pcodemap.img detmask=detmask.img pcodemap=YES<br />
