Parameters

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

Parameter	Mand	Type	Default	Constraints
imageset	yes	string	image
The name of the input image.
srcexp	yes	string
Expression for extracting the source events.
backexp	no	string	NotSet
Expression for extracting the background events. If not set the background value is taken from the parameter backval.
bkgimageset	no	string	NotSet
The name of the background image
exposuremap	no	string	NotSet
The name of the exposure map
backval	no	double	0.0
The background value in cnts per square arcsecond. This value is used if a backexp expression has not been set, otherwise the parameter is ignored.
xcentroid	no	double
Output parameter that contains the X coordinate centroid. This will be in the units of the input image, e.g. sky pixels, detector pixels or degrees.
ycentroid	no	double
Output parameter that contains the Y coordinate centroid. In the units of the input image.
optradius	no	double
Output parameter that contains the optimum extraction radius in the units of the input image (sky pixels, detector pixels or degrees).
optellipxrad	no	double
Output parameter that contains the optimum X radius in the units of the input image (sky pixels, detector pixels or degrees) for an elliptical extraction region.
optellipyrad	no	double
Output parameter that contains the optimum Y radius in the units of the input image (sky pixels, detector pixels or degrees) for an elliptical extraction region.
optelliprot	no	double
Output parameter that contains the rotation angle of the optimum ellipse in degrees.
srccnts	no	double
Output parameter that contains the total src (+backgnd) counts within the source region.
status	no	boolean
Output parameter. This is set to false if the input image was from a Timing or Burst mode observation which eregionanalyse can not yet handle. Otherwise it is set true.
