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 />
