Parameters

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

Parameter	Mand	Type	Default	Constraints
imagesets	yes	dataset list
List of $N$ input images to be summed. They must all have the same pixel dimensions.
outimageset	no	dataset	outimage.ds
The output image, equal to $\sum_{i=1}^N w_i$ imagesets.
tempset	no	dataset	tempimage.ds
Name of a temporary image dataset (for pipeline use).
calculateweights	no	bool	no
If this parameter = `no', the input images are simply summed, and neither background maps or exposure maps are required inputs. Contrariwise for `yes'.
bkgmapsets	yes	dataset list
List of background maps to be summed. They must all have the same pixel dimensions as the imagesets, and there must be the same number of members in each list. Each background map should correspond with the image at the same place in the respective list. This parameter is only read if calculateweights=`yes'.
outbkgmapset	no	dataset	outbkgmap.ds
The output background map, equal to $\sum_{i=1}^N w_i$ bkgmapsets. This parameter is only read if calculateweights=`yes'.
expmapsets	yes	dataset list
List of exposure maps to be summed. They must all have the same pixel dimensions as the imagesets, and there must be the same number of members in each list. Each exposure map should correspond with the image at the same place in the respective list. This parameter is only read if calculateweights=`yes'.
outexpmapset	no	dataset	outexpmap.ds
The output exposure map, equal to $\sum_{i=1}^N w_i$ expmapsets. This parameter is only read if calculateweights=`yes'.
withrelsrcrates	no	bool	no
Whether to read the relative source-count expectation values (`source spectrum') from parameter relsrcrates. If withrelsrcrates=`no', these relative rates are all set to 1. This parameter is only read if calculateweights=`yes'.
relsrcrates	yes	real list	1.0	$0<$relsrcrates
This parameter is read if calculateweights=`yes' and withrelsrcrates=`yes'.
likemin	no	real	10.0	$0<$likemin
The cutoff value of likelihood.
