expimageset2	no	filename	expimage.fits
Name of second input exposure map for option “fitmethod=model”
detmaskset	no	filename	detmask.fits
Name of input detection mask
scut	no	float	0.01	[0.0 $\le param \le$ 10.0]

excesssigma	no	float	4.0	[1.0 $\le param \le$ 6.0]
Threshold for excesses sigmas with respect to background spline fit
nfitrun	no	integer	3	[1 $\le param \le$ 5]

withdetmask	no	boolean	true
Flag to use detection mask
withexpimage	no	boolean	true
Flag to use exposure map
withexpimage2	no	boolean	true

withcheesemask	no	boolean	false
Controls optional output of mask image, value=0 for masked areas, value=1 for valid image areas
cheesemaskset	no	filename	cheesemask.fits
Name of diagnostic output cheese mask image.
withootset	no	boolean	false
Flag to use event table to calculate background due to out-of-time events.
ooteventset	no	filename	events.fits
