Parameters

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

Parameter	Mand	Type	Default	Constraints
Event List Parameters
image	no	string	NULL	valid file name
A name of a fits file that was generated from xmmselect/evselect. No image is used if NULL.
level	no	string	ELLBETA	valid arccuracy level value
Accuracy level: LOW, MEDIUM, EXTENDED, HIGH, ELLBETA
binning	no	int		valid binning value
On-chip-binning factor. Only works for certain camera mode
coordtype	yes	string	TEL	valid coordinate value
Coordinate Type: TEL (theta,phi), DET (detector coords), RAW (chip coords), POS (X,Y - sky coordinates, EQPOS (Ra, Dec), IMPIX (image pixel). The last three (POS,EQPOS,IMPIX) can only be used if an image is supplied.
x	no	real
The X coordinate of the centre of the PSF. If coordtype $=$ TEL, then x is the off-axis angle (theta) which is expected in units of arcseconds. If coordtype $=$ EQPOS then x is the right ascension in units of degrees. For other coordinate systems it should be entered in units of pixels.
y	no	real
The Y coordinate of the centre of the PSF. If coordtype $=$ TEL, then y is the azimuthal angle (phi) which is expected in units of radians. If coordtype $=$ EQPOS then y is the declination in units of degrees. For other coordinate systems it should be entered in units of pixels.
ccdnr	no	int		valid CCD number
CCD number. This is mandatory if coordtype=RAW.
energy	no	real list	3000.0	$\left[ 100:150000\right]$
Energy value list. Note that there is a minimum-maximum range
weight	no	real list	1.0
Weighting to construct summation PSF from multiple PSFs with different energies.
rotate	no	real	0.0	$\left( -1^o:360^o\right)$
Rotation angle of the PSF in units of degrees. If rotate is non-zero then the PSF will be rotated by this angle. The rotation is in the same direction as the position angle (PA). If rotate is not set but an image has been given via the image paremeter then the PSF will be rotated by the position angle (PA_PNT) stored in the image file header. If rotate is non-zero then it will override the value in the input image.
xsize	no	int	199	$\left[ 0:1024\right]$
Width of the X-axis output image in pixels.
ysize	no	int	199	$\left[ 0:1024\right]$
Width of the Y-axis output image in pixels.
output	no	string	psfimage.fits	valid file name
File name of the PSF image.
