Parameters

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

ParameterMand Type Default Constraints
insetyesdatasetfoo.bar 
The image dataset to be smoothed.
 
outsetnodatasetoutimage.ds 
The resulting smoothed data set.
 
copydssnobooleanyesyes/no
Whether to look for a DSS in the input image set and copy it to the smoothed image set.
 
smoothtypenostring`adaptive'simple|adaptive
The type of smoothing desired.
 
sigmanoreal1.0 pixels0.0 $<$ sigma$<$ 30.0 pixels
If smoothtype='simple' is chosen, the value of the width $\sigma$ of the smoothing gaussian is specified via this parameter.
 
ngaussnointeger202 $<$ ngauss$<$ 126
If smoothtype='adaptive' is chosen, the maximum number of gaussian smoothing kernels is specified via this parameter.
 
minsigmanoreal0.0 pixels0.0 $<$ 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.
 
maxsigmanoreal5.0 pixels0.0 $<$ 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.
 
desiredsnrnoreal10.01.0 $<$ desiredsnr
If smoothtype=`adaptive' is chosen, the maximum desired signal-to-noise ratio of the output image can be specified via this parameter.
 
readtemplatesetnobooleannoyes/no
Before beginning (adaptive) smoothing, read from the template set specified by templateset.
 
writetemplatesetnobooleanyesyes/no
After completion of (adaptive) smoothing, write to the template set specified by templateset.
 
templatesetnodatasettemplate.dsnone
Name of the template image to be read and/or written.
 
withvariancesetnobooleannoyes/no
Look for the name of a variance image on the command line.
 
variancesetnodataset none
Name of the variance image.
 
withinmasksetnobooleannoyes/no
Look for the name of a weighting mask image on the command line.
 
inmasksetnodataset none
Name of the weighting mask image.
 
withoutmasksetnobooleannoyes/no
Look for the name of a clipping mask image on the command line.
 
outmasksetnodataset none
Name of the clipping mask image.
 
writebadmasksetnobooleannoyes/no
Write the badmaskset.
 
badmasksetnodatasetbadpix.dsnone
Name of the map of pixels which were unable to be smoothed because the weight was too low.
 
withsrclistsetnobooleannoyes/no
Look for the name of a source list on the command line.
 
srclistsetnodataset none
Name of the source list (the output of either eboxdetect or emldetect can be used).
 
expressionnostring`ID_BAND==0'none
Source selection expression.
 
racolnostringRAnone
Name of the column in the source list from which to get RAs.
 
deccolnostringDECnone
Name of the column in the source list from which to get Decs.
 
ratecolnostringSCTSnone
Name of the column in the source list from which to get source brightness.
 
bkgratecolnostringBG_MAPnone
Name of the column in the source list from which to get background count rate.
 
bkgfractionnoreal1.0$> 0$
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.
 
writecheesemasksetnobooleannoyes/no
Write the cheesemaskset.
 
cheesemasksetnodatasetcheese.dsnone
Name of the image which records the weighting mask after source holes have been cut from it.
 
withexpimagesetnobooleannoyes/no
Look for the name of an exposure map image on the command line.
 
expimagesetnodataset none
Name of the exposure map image.
 
expmapusenostringsamesizesamesize|samesnr
Controls the appearence of a smoothed image which had exposure variations (see subsubsection 3.1.4). Inactive unless withexpimageset=yes.
 
remultiplynobooleannoyes/no
This parameter instructs asmooth to remultiply the smoothed output image by the exposure map. Inactive unless withexpimageset=yes.
 
forcecalctypenobooleannoyes/no
Force the use of either all direct processing or all Fourier-domain (see developers' notes).
 
calcbyfftnobooleanyesyes/no
If is set, this parameter controls which of the two types to use: Fourier domain if true, direct otherwise (see developers' notes).
 
nopslimitnoreal$250000$$> 0$
See developers' notes.
