Parameters

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

ParameterMand Type Default Constraints
imagesetyesstringimage.fits 
Name of the input fits image.
 
srclistsetnostringewavlist.fits 
Output data set containing the wavelet source list.
 
expmapsetnostringexpmap.fits 
Name of the input fits image containing the exposure map.
 
useexpmapnobooleantrue 
Use an external exposure map or not (in case no proper exposure map is available).
 
minscalenoreal2.0$1.0$$16.0$
Minimum wavelet scale.
 
maxscalenoreal8.0$2.0$$32.0$
Maximum wavelet scale.
 
thresholdnoreal53–7
Detection threshold in $\sigma$, only sources with a significance larger than this threshold will be stored. The choice of the threshold will also influence the parameters of sources above the threshold, since the background estimate depends on the number of detected sources.
 
edgethresholdnoreal4.00.0–10.0
Controls the suppression of spurious detection near sharp edges in the exposure mask. The exposure mask is convolved with the MH function and only regions, where the resulting image value is less than edgethreshold, are used for detection. Small values lead to better suppression of spurious sources, but also real sources near edges might be missed. With edgethreshold=1.0, no sources will be rejected.
 
niternointeger22–4
Number of iterations to be used.
 
makereconnobooleanfalse 
Boolean controlling whether an image with detected sources represented by Gaussians will be saved as a fits image.
 
recimagesetnostringreconstruction.fits 
Name of output fits image containing the reconstructed input image. See also parameter makerecon.
 
savebkgrndnobooleanfalse 
Boolean controlling whether the final background image will be saved as a fits image.
 
bkgrndsetnostringbackground.fits 
Name of the fits output image containing the final background image.
 
withinputlistnobooleanfalse 
Boolean controlling whether reconstruction and/or background image will be derived from an input source list (parameter inputlist) . If set to “true”, no source detection will be performed.
 
inputlistnostringewavlist.fits 
If withinputlist=“true”, this file will be used as input source list.
