Parameters

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

Parameter	Mand	Type	Default	Constraints
xrayset	yes	set
File name for the fits binary table containing X-ray source positions and their errors.
opticalset	yes	set
File name for the fits binary table containing optical source positions and their errors.
findrotation	no	boolean	no
Search for a rotational offset or not?
niter	no	integer	3	1-8
Once a solution is found a new iteration can be made using a smaller grid size. This parameter determines the number of iterations.
maxoffset	no	real	8.0	4.0-15.0
Constraint on the maximum RA/DEC offset.
maxrotation	no	real	1.0	0.5-4.0
Constraint on the maximum rotational offset.
maxdist	no	real	20.0	10.0-120.0
All optical sources with distances $>$ maxdist will be removed from the source list, in order to speed up the correlation.
maxposnerr	no	real	20.0	1.0-120.0
neglect xray sources with positional errors $>$ maxposnerr in position fitting in order to get a closer match to the real positions on the sky.
usemaxdist	no	boolean	yes
Use maxdist to make a preselection of optical sources?
minbmagn	no	real	0.0	-2.0-30.0
Preselect the optical list on basis of B Magnitude. Here the mininum is set.
maxbmagn	no	real	26.0	-2.0-30.0
Preselect the optical list on basis of B Magnitude. Here the maximum is set.
usebmagn	no	boolean	no
Use the B magnitude to make a preselection of optical sources?
bmag	no	string	Bmagn
name of B magnitude column
minrmagn	no	real	0.0	-2.0-30.0
Preselect the optical list on basis of R Magnitude. Here the mininum is set.
maxrmagn	no	real	26.0	-2.0-30.0
Preselect the optical list on basis of R Magnitude. Here the maximum is set.
usermagn	no	boolean	no
Use the R magnitude to make a preselection of optical sources?
rmag	no	string	Rmagn
name of R magnitude column
makeimage	no	boolean	no

xrayradecerr	no	string	RADEC_ERR
column name of X-ray source position error
xraytableext	no	string	SRCLIST
X-ray source list fits table extension
calculateoffsets	no	boolean	yes

decoffset	no	real	0.0
DEC offset (arcsec) to be used if calculateoffsets=no
rotation	no	real	0.0
