Parameters

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

Parameter	Mand	Type	Default	Constraints
bkgmapsets	yes	dataset
The list of $N$ background maps $B_i$ used in the eboxdetect source detection run.
expmapsets	yes	dataset
The list of $N$ exposure maps $\epsilon_i$ used in the eboxdetect source detection run.
weights	yes	real		$0\le$weights
The detected spectrum of the source (that is, the x-ray spectrum multiplied by the instrument response function) as represented by $N$ weights, the $i$th weight $\mu_i$ representing the total number of detected counts within energy band $i$ during a given exposure time, on the optic axis, assuming no chip gaps or bad pixels under the PSF.
sensmapsets	yes	dataset
The list of $N$ output sensitivity maps (maps of the lowest detectable point-source count rate).
likemin	yes	real		$0<$likemin
The same cutoff value of detection likelihood $L_{\rm {cutoff}}$ which was supplied to the parameter of the same name of eboxdetect.
boxhalfsize	yes	integer		$0\le$boxhalfsize
This should match the value of -boxsize supplied to eboxdetect. Suppose -boxsize=$b$; the corresponding value of boxhalfsize should be $(b-1)/2$. Note that -boxsize as presently defined in eboxdetect is always odd.
naxial	no	integer	36	$4\le$naxial
This parameter is passed to econvolverprep and a description of its effects should be sought therein.
nradial	no	integer	10	$1\le$nradial
This parameter is passed to econvolverprep and a description of its effects should be sought therein.
psfestyle	no	string	user	user|dss
The task needs to know the mean values of the energy bands of the $N$ input images $I_i$ to eboxdetect. There are two ways in which this information can be supplied to esensitivity: either directly via the parameter psfenergies, or via data subspace (DSS) records of all event selections within the image datasets themselves as supplied to the parameter dssimagesets. NOTE that the inclusion of a DSS in XMM EPIC images is optional, thus these may not be present.
psfenergies	yes	real		$1\le$psfenergies
If psfestyle=`user', the task seeks a list of $N$ mean energy values in the present parameter.
dssimagesets	yes	dataset
If psfestyle=`dss', the task seeks a list of $N$ mean energy values in the data subspaces of the $N$ datasets $I_i$ supplied to the present parameter.
astest	no	boolean	no
Set this to `yes' if you want to test the perl script esensitivity without invoking any child processes (ftools or other sas tasks).
