Parameters

This section documents the parameters recognized by this task (if any).

Parameter	Mand	Type	Default	Constraints
inset	yes	dataset	foo.bar
The image dataset to be smoothed.
outset	no	dataset	outimage.ds
The resulting smoothed data set.
copydss	no	boolean	yes	yes/no
Whether to look for a DSS in the input image set and copy it to the smoothed image set.
smoothtype	no	string	`adaptive'	simple|adaptive
The type of smoothing desired.
sigma	no	real	1.0 pixels	0.0 $<$ sigma$<$ 30.0 pixels
If smoothtype='simple' is chosen, the value of the width $\sigma$ of the smoothing gaussian is specified via this parameter.
ngauss	no	integer	20	2 $<$ ngauss$<$ 126
If smoothtype='adaptive' is chosen, the maximum number of gaussian smoothing kernels is specified via this parameter.
minsigma	no	real	0.0 pixels	0.0 $<$ minsigma$<$ 20.0 pixels
If smoothtype=`adaptive' is chosen, the minimum allowed value of the width $\sigma$ of the smoothing gaussian is specified via this parameter.
maxsigma	no	real	5.0 pixels	0.0 $<$ maxsigma$<$ 20.0 pixels
If smoothtype='adaptive' is chosen, the maximum allowed value of the width $\sigma$ of the smoothing gaussian is specified via this parameter.
desiredsnr	no	real	10.0	1.0 $<$ desiredsnr
If smoothtype=`adaptive' is chosen, the maximum desired signal-to-noise ratio of the output image can be specified via this parameter.
readtemplateset	no	boolean	no	yes/no
Before beginning (adaptive) smoothing, read from the template set specified by templateset.
writetemplateset	no	boolean	yes	yes/no
After completion of (adaptive) smoothing, write to the template set specified by templateset.
templateset	no	dataset	template.ds	none
Name of the template image to be read and/or written.
withvarianceset	no	boolean	no	yes/no
Look for the name of a variance image on the command line.
varianceset	no	dataset		none
Name of the variance image.
withinmaskset	no	boolean	no	yes/no
Look for the name of a weighting mask image on the command line.
inmaskset	no	dataset		none
Name of the weighting mask image.
withoutmaskset	no	boolean	no	yes/no
Look for the name of a clipping mask image on the command line.
outmaskset	no	dataset		none
Name of the clipping mask image.
writebadmaskset	no	boolean	no	yes/no
Write the badmaskset.
badmaskset	no	dataset	badpix.ds	none
Name of the map of pixels which were unable to be smoothed because the weight was too low.
withsrclistset	no	boolean	no	yes/no
Look for the name of a source list on the command line.
srclistset	no	dataset		none
Name of the source list (the output of either eboxdetect or emldetect can be used).
expression	no	string	`ID_BAND==0'	none
Source selection expression.
racol	no	string	RA	none
Name of the column in the source list from which to get RAs.
deccol	no	string	DEC	none
Name of the column in the source list from which to get Decs.
ratecol	no	string	SCTS	none
Name of the column in the source list from which to get source brightness.
bkgratecol	no	string	BG_MAP	none
Name of the column in the source list from which to get background count rate.
bkgfraction	no	real	1.0	$> 0$
This parameter is only required if withsrclistset=yes. It is used to calculate the size of the holes to make at each source position: the larger the value of bkgfraction, the larger will be the holes.
writecheesemaskset	no	boolean	no	yes/no
Write the cheesemaskset.
cheesemaskset	no	dataset	cheese.ds	none
Name of the image which records the weighting mask after source holes have been cut from it.
withexpimageset	no	boolean	no	yes/no
Look for the name of an exposure map image on the command line.
expimageset	no	dataset		none
Name of the exposure map image.
expmapuse	no	string	samesize	samesize|samesnr
Controls the appearence of a smoothed image which had exposure variations (see subsubsection 3.1.4). Inactive unless withexpimageset=yes.
remultiply	no	boolean	no	yes/no
This parameter instructs asmooth to remultiply the smoothed output image by the exposure map. Inactive unless withexpimageset=yes.
forcecalctype	no	boolean	no	yes/no
Force the use of either all direct processing or all Fourier-domain (see developers' notes).
calcbyfft	no	boolean	yes	yes/no
If is set, this parameter controls which of the two types to use: Fourier domain if true, direct otherwise (see developers' notes).
nopslimit	no	real	$250000$	$> 0$
See developers' notes.
